Definitions
[0092] While various embodiments of the invention have been shown and described herein, it will be obvious to those skilled in the art that such embodiments are provided by way of example only. Numerous variations, changes, and substitutions may occur to those skilled in the art without departing from the invention. It should be understood that various alternatives to the embodiments of the invention described herein may be employed.
[0093] The practice of some methods disclosed herein employ, unless otherwise indicated, techniques of immunology, biochemistry, chemistry, molecular biology, microbiology, cell biology, genomics and recombinant DNA. See for example Sambrook and Green, Molecular Cloning: A Laboratory Manual, 4th Edition (2012); the series Current Protocols in Molecular Biology (F. M. Ausubel, et al. eds.); the series Methods In Enzymology (Academic Press, Inc.), PCR 2: A Practical Approach (M.J. MacPherson, B.D. Hames and G.R. Taylor eds. (1995)), Harlow and Lane, eds. (1988) Antibodies, A Laboratory Manual, and Culture of Animal Cells: A Manual of Basic Technique and Specialized Applications, 6th Edition (R.I. Freshney, ed. (2010)) (which is entirely incorporated by reference herein).
[0094] As used herein, the singular forms “a,” “an,” and “the” are intended to include the plural forms as well, unless the context clearly indicates otherwise. Furthermore, to the extent that the WSGR Docket No. 52459-726.601 terms “including,” “includes,” “having,” “has,” “with,” or variants thereof are used in either the detailed description and/or the claims, such terms are intended to be inclusive in a manner similar to the term “comprising.”
[0095] The term “about” or “approximately” means within an acceptable error range for the particular value as determined by one of ordinary skill in the art, which will depend in part on how the value is measured or determined, i.e., the limitations of the measurement system. For example, “about” can mean within one or more than one standard deviation, per the practice in the art. Alternatively, “about” can mean a range of up to 20%, up to 15%, up to 10%, up to 5%, or up to 1% of a given value.
[0096] The term “nucleotide,” as used herein, generally refers to a base-sugar-phosphate combination. A nucleotide may comprise a synthetic nucleotide. A nucleotide may comprise a nucleotide analog. A nucleotide may comprise a synthetic nucleotide analog. Nucleotides may be monomeric units of a nucleic acid sequence (e.g., deoxyribonucleic acid (DNA) and ribonucleic acid (RNA)). The term nucleotide may include ribonucleoside triphosphates adenosine triphosphate (ATP), uridine triphosphate (UTP), cytosine triphosphate (CTP), guanosine triphosphate (GTP) and deoxyribonucleoside triphosphates (dNTPs) such as dATP, dCTP, diTP, dUTP, dGTP, dTTP, or derivatives thereof. Such derivatives may include, for example, [aS]dATP, 7-deaza-dGTP and 7-deaza-dATP, and nucleotide derivatives that confer nuclease resistance on the nucleic acid molecule containing them. Synthetic nucleotide analogs may include locked nucleic acids (LNAs), bridged nucleic acids (BNAs), fluorinated nucleic acids (also known as fluoro-modified nucleic acids), and peptide nucleic acids (PNAs). As used herein, the term “locked nucleic acid” (“LNA”), generally refers to a nucleic acid analog wherein the ribose ring is “locked” with an extra bridge connecting the 2 -oxygen atom with the 4'-carbon atom of the nucleotide such as a methylene bridge (see e.g. WO 99/14226, which is incorporated by reference in its entirety herein). As used herein, the term “bridged nucleic acid (BNA),” generally refers to constrained or inaccessible nucleic acid molecules which have a fixed bridge structure at the 2'- or 4'-position. As used herein, “fluorinated nucleic acids” generally refer to nucleic acids which have incorporated a fluorine atom, often at the 2'- or mposition. As used herein, the term “peptide nucleic acid (PNA),” generally refers to a nucleotide analog wherein the backbone of the analog, for example a sugar backbone in DNA, is a pseudopeptide. A PNA backbone can comprise, for example, a sequence of repeated N-(2- amino-ethyl)-glycine units. A peptide nucleic acid analog can react as DNA would react in a given environment, and can additionally bind complementary nucleic acid sequences and WSGR Docket No. 52459-726.601 various proteins. Due to the non-natural backbone, PNAs can be insensitive to endonuclease cleavage in situations where an endonuclease would cleave the equivalent DNA/RNA sequence. The term “nucleotide,” as used herein, may refer to dideoxyribonucleoside triphosphates (ddNTPs) and their derivatives. Illustrative examples of dideoxyribonucleoside triphosphates may include, but are not limited to, ddATP, ddCTP, ddGTP, ddITP, and ddTTP. A nucleotide may be unlabeled or detectably labeled, such as using moieties comprising optically detectable moieties (e.g., fluorophores). Detectable labels may include, for example, radioactive isotopes, fluorescent labels, chemiluminescent labels, bioluminescent labels and enzyme labels.
[0097] The terms “polynucleotide,” “oligonucleotide,” and “nucleic acid” are used interchangeably to generally refer to a polymeric form of nucleotides of any length, either deoxyribonucleotides or ribonucleotides, or analogs thereof, either in single-, double-, or multistranded form. A polynucleotide may be DNA. A polynucleotide may be RNA. A polynucleotide may comprise one or more nucleotide analogs (e.g., including those with an altered backbone, sugar, or nucleobase). If present, modifications to the nucleotide structure may be imparted before or after assembly of the polymer. Some non-limiting examples of analogs include: 5-bromouracil, peptide nucleic acid, xeno nucleic acid, morpholinos, glycol nucleic acids, threose nucleic acids, dideoxynucleotides, cordycepin, 7-deaza-GTP, fluorophores (e.g., rhodamine or fluorescein linked to the sugar), thiol containing nucleotides, biotin linked nucleotides, fluorescent base analogs, CpG islands, methyl-7-guanosine, methylated nucleotides, inosine, thiouridine, pseudourdine, dihydrouridine, queuosine, wyosine, PNAs, and LNAs.
[0098] As used herein, the term “restriction endonuclease,” “restriction enzyme,” or grammatical equivalents thereof generally refers to an enzyme that originates in bacterial host defense and is understood to recognize a specific sequence on an incoming viral DNA and cleave the DNA either at the recognition sequence or at a distinct sequence site. One group of restriction endonucleases are identified as Type IIS. This group can recognize asymmetric DNA sequences and cleaves the DNA at a site outside the cleavage site that is at a defined distance from the recognition site. In some cases, type IIS restriction endonucleases cleave DNA between 1 and 20 nucleotides from the relevant recognition site.
[0099] As used herein, the term “restriction endonuclease recognition sequence” generally refers to a location on a nucleic acid molecule (e.g., DNA molecule) containing specific sequences of nucleotides, which are recognized by various restriction enzymes. These sequences can WSGR Docket No. 52459-726.601 comprise from 4-8 base pairs to 12-40 base pairs in length. These sites can be palindromic sequences.
[00100] As used herein, the term “sample” refers to a substance (e.g., solid or liquid) that contains a target nucleic acid sequence to be amplified. The target nucleic acid may be DNA. The target nucleic acid molecule may be RNA. As used herein, a “processed sample” refers to a sample that has been contacted by a lysis buffer and/or a recovery buffer of the present disclosure.
[00101] As used herein, the term “template” generally refers to a portion of a target RNA or DNA of a sample that is amplified by a DNA polymerase to produce one or more amplified nucleic acid products.
[00102] As used herein, “amplified product”, “amplified nucleic acid product”, or “amplicon” generally refers to the end product resulting from a nucleic acid method, such as PCR or isothermal amplification.
[00103] As used herein, the term “polymerase” generally refers to an enzyme that produces a complementary replicate of a nucleic acid molecule using the nucleic acid as a template strand. DNA polymerases bind to the template strand and then move down the template strand adding nucleotides to the free hydroxyl group at the 3' end of a growing chain of nucleic acid. DNA polymerases synthesize complementary DNA molecules from DNA (e.g. DNA-dependent DNA polymerases) or RNA templates (e.g. RNA-dependent DNA polymerases or reverse transcriptases) and RNA polymerases synthesize RNA molecules from DNA templates (e.g. DNA-dependent RNA polymerases which participate in transcription). DNA polymerases generally use a short, preexisting RNA or DNA strand, called a primer, to begin chain growth. Some DNA polymerases replicate single-stranded templates, while other DNA polymerases displace the strand upstream of the site where they add bases to a chain.
[00104] As used herein, the term “strand displacing,” when used in reference to a polymerase, generally refers to an activity that removes a complementary strand from base-pairing with a template strand being read by the polymerase. Example polymerases having strand displacing activity include the large fragment of Bacillus stearothermophilus polymerase, exo-Klenow polymerase, B st 2.0 polymerase, B st 3.0 polymerase, SD DNA polymerase, phi29 DNA polymerase, and sequencing-grade T7 exo-polymerase.
[00105] As used herein, “primer”, or “primer sequence” generally refers to a linear oligonucleotide that is complementary to and anneals to a target sequence. The lower limit on primer length is determined by ability to hybridize since very short primers (e.g., less than 5 WSGR Docket No. 52459-726.601 nucleotides) do not form thermodynamically stable duplexes under most hybridization conditions. Primers may vary in length from 4 to 50 nucleotides. In some embodiments, the primer is between about 10 and 20 nucleotides in length. In some embodiments, the primer can be more than about 100 nucleotides in length. In some embodiments, the primer can be an oligonucleotide that can hybridize with a target nucleic acid sequence. In some embodiments, the primer can be a probe. In some embodiments, the primer can comprise a guide oligonucleotide. For example, the primer (e.g., the guide oligonucleotide) can be an oligonucleotide comprising a target binding region that hybridizes to a target polynucleotide sequence and a non-target binding region that does not hybridize to a target sequence. In some embodiments, the non-target binding region of the primer can comprise a palindromic sequence. In some embodiments, the palindromic sequence may permit recruitment of binding of a restriction enzyme to process the target sequence.
[00106] As used herein, the terms “amplify,” “amplifies,” “amplified,” “amplification,” and “amplicon” generally refer to any method for replicating a nucleic acid. The replication can be conducted with the use of a primer-dependent polymerase. The replication can be enzyme-free amplification. In some cases, amplifying or replicating a target nuclei acid strand also comprises replicating or amplifying a complementary strand of the target nucleic acid strand. Amplified products can be subjected to subsequence analyses, including but not limited to melting curve analysis, nucleotide sequencing, single-strand conformation polymorphism assay, allele-specific oligonucleotide hybridization, Southern blot analysis, and restriction endonuclease digestion.
[00107] The terms “hybridizes,” and “annealing,” as used herein, generally refer to a reaction in which one or more polynucleotides interact to form a complex that is stabilized via hydrogen bonding between the bases of the nucleotide residues. The hydrogen bonding may occur by Watson Crick base pairing, Hoogstein binding, or in any other sequence sensitive or specific manner. The complex may comprise two strands forming a duplex structure, three or more strands forming a multi stranded complex, a single self-hybridizing strand, or any combination of these. A hybridization reaction may constitute a step in a more extensive process, such as the initiation of a PCR, or the enzymatic cleavage of a polynucleotide by a ribozyme. A first sequence that can be stabilized via hydrogen bonding with the bases of the nucleotide residues of a second sequence can generally be “hybridizable” to the second sequence. In such a case, the second sequence can also be the to be hybridizable to the first sequence. WSGR Docket No. 52459-726.601
[00108] The terms “complement,” “complements,” “complementary,” and “complementarity,” as used herein, generally refer to a sequence that is fully complementary to and hybridizable to the given sequence. In some cases, a first sequence that is hybridizable to a second sequence or set of second sequences is specifically or selectively hybridizable to the second sequence or set of second sequences, such that hybridization to the second sequence or set of second sequences is used. Hybridizable sequences can share a degree of sequence complementarity over all or a portion of their respective lengths, such as between 25%-100% complementarity, including at least about 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98%, 99%, and 100% sequence complementarity.

The compositions, methods, and kits described herein, and uses thereof, can be designed to be flexible and adaptable, reducing the time necessary to develop products.
[00110] The buffer compositions described herein, e.g., lysis buffers, recovery buffers, amplifications and/or stabilization buffers, can be versatile and can function with various component concentrations.
[00111] The compositions and methods described herein can be used to process various samples and can function in the presence of any inhibitors that may be present in a sample.
[00112] Compositions described herein can be part of an amplification buffer system, a sample processing buffer system, a stabilization buffer system, or any combination thereof. The amplification buffer (e.g., core amplification buffer) can comprise enzymes, primers and/or probes (e.g., guide oligonucleotides), reverse transcriptase primers, molecular beacons, dNTPs, or any combination thereof. The sample processing buffer (e.g., Sample Direct) can comprise reagents of lysis and/or recovery buffers described herein. The sample processing buffer can comprise salts and/or buffers which may be adjusted to optimize amplification reactions (e.g., PCR and/or isothermal amplification). The stabilization buffer can comprise cyclodextrin, WSGR Docket No. 52459-726.601 protein stabilizers, cake structure modifiers (Tc, Tg, Tg’), salts, buffers, or any combination thereof.

[00151] In some embodiments, the composition comprises a cyclodextrin. The cyclodextrin is configured to form a complex with the detergent of the present application. Without wishing to be bound by theory, the complex formed between the cyclodextrin and detergent assists in stabilizing the enzyme in the composition. The cyclodextrin increases the efficiency of forming the complex. As a complexing agent, the cyclodextrin can increase the aqueous solubility of poorly soluble drugs and increase bioavailability and stability in solution. In some embodiments, the cyclodextrin comprises (2-hydroxypropyl) P-cyclodextrin, (2-hydroxypropyl) y-cyclodextrin, (2-hydroxypropyl)-a-cyclodextrin, 3A-amino-3A-deoxy-(2AS,3AS)-a-cyclodextrin hydrate, monopropanediamino-P-cyclodextrin, 6-O-alpha-D-Maltosyl-P-cyclodextrin, 2,6-Di-O-methyl- P-cyclodextrin, hydroxyethyl-P-cyclodextrin, 3A-amino-3A-deoxy-(2AS,3AS)-P-cyclodextrin hydrate, 3 A-amino-3A-deoxy-(2AS,3AS)-y-cyclodextrin hydrate, or any combination thereof. The cyclodextrin can comprise an anionic cyclodextrin. The anionic cyclodextrin may comprise WSGR Docket No. 52459-726.601 carboxymethyl-a-cyclodextrin, carboxymethyl-P-cyclodextrin, succinyl-a-cyclodextrin, succinyl-P-cyclodextrin, succinyl-y-cyclodextrin, (2-carboxyl)-a-cyclodextrin, (2-carboxyl)-P- cyclodextrin, a-cyclodextrin phosphate, P-cyclodextrin phosphate, y-cyclodextrin phosphate, sulfobutylated P-cyclodextrin, a-cyclodextrin sulfate, P-cyclodextrin sulfate, y-cyclodextrin sulfate, carboxymethyl-y-cyclodextrin, (2-carboxyl)-y-cyclodextrin, sulfobutylated-a- cyclodextrin, succinyl-(2-hydroxypropyl)-P cyclodextrin, succinyl-(2-hydroxypropyl)-y cyclodextrin, sulfobutylated-y cyclodextrin, methyl-P-cyclodextrin, or any combination thereof. In some embodiments, the cyclodextrin in the recovery buffer can comprise two or more different cyclodextrin species described herein. For example, the cyclodextrin in the recovery buffer can comprise (2-hydroxypropyl) p-cyclodextrin and (2-hydroxypropyl) y-cyclodextrin. For another example, the cyclodextrin in the recovery buffer can comprise (2-hydroxypropyl) a- cyclodextrin and methyl-P-cyclodextrin. In some cases, the cyclodextrin in the recovery buffer can comprise (2-hydroxypropyl) P-cyclodextrin and methyl-P-cyclodextrin. In some cases, altering the molar substitution ratio of a particular modified cyclodextrin species (e.g., (2- hydroxypropyl) P-cyclodextrin, methyl-P-cyclodextrin, etc.) may improve reaction performance such as shortening time to result values, Ct values, or Cq values.

[00204] In some embodiments, a composition (e.g., a recovery buffer) described herein may comprise one or more cucurbituril. Cucurbiturils are macrocyclic molecules made of glycoluril monomers linked by methylene bridges. Cucurbiturils may form host guest complexes in a composition described herein. Without wishing to be bound by theory, cucurbiturils may be advantageous in a sample preparation as they host one or more inhibitory substances in samples (e.g., PAX samples) so that the samples may be run directly without purification. The PAX sample, as used herein, refers to a sample collected in a PAXgene® tube (or PAX tube as used here). The sample collected in the PAXgene® tube can be directly used for further sample processing or subject to amplification reactions using the amplification buffers described herein. The PAXgene® Blood RNA tube comprises one or more solutions configured to stabilize intracellular RNA. In some cases, the PAXgene® Blood RNA tube can comprise tetradecyl trimethyl -ammonium oxalate and/or tartaric acid. To use the PAXgene® Blood RNA tube, the sample may undergo centrifugation. Use of the compositions and/or methods described herein WSGR Docket No. 52459-726.601 comprising one or more of the buffers described herein may remove the need to centrifuge a sample for sample processing, sample stabilization, and/or sample amplification. In some embodiments, the compositions and/or methods described herein comprising one or more of the buffers described herein can improve stabilization of genetic material (e.g., RNA) compared to that of the PAXgene® Blood RNA system. The use of the compositions and/or methods described herein may enhance stabilization of genetic material (e.g., RNA) to improve quality of an amplified genetic product, reduce time to produce an amplified product, or any combination thereof.

Nucleic Acid Amplifications
[00325] The compositions and methods provided herein can be used for processing samples that are used in various down-stream operations, including nucleic acid amplifications. Various nucleic acid amplifications can be used including polymerase chain reactions and isothermal amplifications. The nucleic acid amplification described herein may generate an amplified processed sample. In some embodiments, a time period of a nucleic acid amplification described herein to generate an amplified processed sample can be at most about 10 minutes, at most about 9 minutes, at most about 8 minutes, at most about 7 minutes, at most about 6 minutes, at most about 5 minutes, at most about 4 minutes, at most about 3 minutes, at most about 2 minutes, at most about 1 minute, at most about 50 seconds, at most about 40 seconds, at most about 30 seconds, at most about 20 seconds, at most about 15 seconds, at most about 10 seconds, or less than about 10 seconds.
Polymerase Chain Reaction
[00326] The nucleic acid amplification described herein can be a Polymerase Chain Reaction (PCR). A sample (e.g., DNA) containing the nucleic acid sequence to be amplified can be heated WSGR Docket No. 52459-726.601 to denature or separate the two strands of the nucleic acid. The sample can then be cooled and mixed with specific oligonucleotide primers, allowing annealing of the primers to the singlestranded DNA template. Following this hybridization, a thermostable DNA polymerase in a reaction mixture can be added to the sample, along with free dNTPs that are linked by the polymerase to the replicating nucleic acid strand. After allowing polymerization to proceed to completion, the products can again be heated to separate the strands and subjected to another round of primer hybridization and polymerase replication. This process can be repeated any number of times. Since each nucleic acid product of a given cycle of this process can serve as a template for production of two new nucleic acid molecules (one from each parent strand), the PCR process can result in an exponential increase in the concentration of the target sequence. Thus, in a well-controlled, high-fidelity PCR process, as few as 20 cycles can result in an over one million fold amplification of the target nucleic acid sequence. Thermostable DNA Polymerases
[00327] In nucleic acid amplification techniques, thermostable DNA polymerases can be used to synthesize a new DNA strand complementary to the DNA template strand. The thermostable DNA polymerase most commonly used in PCR is Taq polymerase, isolated from the thermophilic bacterium Thermus aquaticus. Taq polymerase can function at temperatures of 70- 80°C, and can maintain substantial activity upon repeated exposure to temperatures of 92°-95°C. [00328] In addition to Taq polymerase, other thermostable polymerases may be used. Alternatives for Taq polymerase in PCR are known in the art and include polymerases isolated from the thermophilic bacteria Thermus thermophilus (Tth polymerase), Thermococcus litoralis (Tli or VENT™ polymerase), Pyrococcus furiosus (Pfu or DEEP VENT polymerase), Pyrococcus woosii (Pwo polymerase) and other Pyrococcus species, Bacillus sterothermophilus (Bst polymerase), Sulfolobus acidocaldarius (Sac polymerase), Thermoplasma acidophilum (Tac polymerase), Thermus flavus (Tfl/Tub polymerase), Thermus ruber (Tru polymerase), Thermus brockianus (DYNAZYME™ polymerase), Thermotoga neapolitana (Tne polymerase), Thermotoga maritima (Tma polymerase) and other species of the Thermotoga genus (Tsp polymerase) and Methanobacterium thermoautotrophicum (Mth polymerase).
Isothermal Amplification
[00329] Isothermal amplification can rapidly and efficiently copy nucleic acids without temperature changing cycles. Instead, isothermal amplification can use specific DNA polymerases, and specially designed primer sets to exponentially amplify a target sequence. Different isothermal amplification methods can utilize different DNA polymerases. Helicase- WSGR Docket No. 52459-726.601 dependent amplification (HD A) can use helicase to unwind DNA, allowing primers to bind. Two accessory proteins, MutL and single-stranded DNA-binding protein (SSB), can be used to prevent complimentary strands from associating. Isothermal multiple displacement amplification (IMDA) can use strand-displacing DNA polymerase and multiple primer sets. Particular advantages of IMDA may include increased sensitivity and specificity. Loop-mediated isothermal amplification (LAMP) can use 4-6 primers and a strand-displacing DNA polymerase. LAMP is a highly efficient amplification method that can synthesize a large quantity of DNA in a short period of time. Recombinase polymerase amplification (RPA) can use recombinase, primers, SSB, and a strand-displacing DNA polymerase to amplify DNA. Recombinase may be complexed with the primer and the complex then can use strand exchange to bind to doublestranded DNA. After the strand exchange an SSB T4 gp32 can stabilize the displaced strand. Rolling circle amplification (RCA) can synthesize long single-stranded DNA using a short, circular single-stranded DNA template and a single primer. RCA can use a strand-displacing DNA polymerase called phi 29. Single primer isothermal amplification (SPIA) may use only one DNA-RNA chimeric primer along with RNAase H and a strand-displacing DNA polymerase. Strand displacement amplification may rely on a restriction enzyme (Hindi) and an exonuclease-deficient DNA polymerase. HinCII can nick the target DNA, and the DNA polymerase can then extend the 3’ end.
[00330] The methods, compositions, and kits described herein can be used for processing target nucleic acid molecules. In some aspects, the present disclosure provides for methods of amplification of nucleic acids (e.g., isothermal amplification). Such a method can involve a cycle of steps such as that depicted in FIGs. 15A through 150. The compositions and methods as shown in FIGs. 15A through 150 can be referred to as differential targeted endonuclease cutting technology (DTECT). The methods provided herein can offer higher amplification efficiency and easier optimization procedure compared with existing amplifications (e.g. isothermal amplifications). Additional details of the isothermal application methods described herein are disclosed in the International Application No. PCT/US2023/079306, which is incorporated herein by reference in its entirety. The processed target nucleic acid molecules can be used in various amplification reactions not limited to the amplification or processing methods described herein.
[00331] The DTECT method described herein can start with the formation of a structure such as that depicted in FIG. 15A, in which a guide nucleic acid complex (or a guide complex) is formed to direct a restriction enzyme to a predetermined site in a nucleic acid. FIG. 15A depicts WSGR Docket No. 52459-726.601 a nucleic acid strand (e.g., a single-stranded DNA strand or ssDNA strand) (100) comprising a target nucleic acid sequence (101). In some cases, the ssDNA strand can be generated by reverse transcribing a target RNA sequence. In some cases, the ssDNA strand can be generated by denaturing a double-stranded DNA (dsDNA) sequence. In FIG. 15A, a type Ils restriction enzyme (120) is directed to the vicinity of the target site via formation of a guide complex. This guide nucleic acid complex is constituted via self-annealing of single copies of a guide polynucleotide which comprise: a non-target binding region comprising a restriction endonuclease recognition sequence for a type Ils restriction enzyme (117), a target binding region configured to hybridize to the target sequence (115), and a blocked 3' end non-extendable by a polymerase (116). Note that in FIG. 15A, self-annealing of the two copies of the guide polynucleotide forms a double-stranded palindromic region that permits binding of the type II restriction enzyme in the vicinity of the target site.
[00332] The DTECT method described herein can continue in a second stage with the process depicted in FIG. 15B and FIG. 15C. After the type Ils restriction enzyme (120) is directed to the vicinity of the target site (101) by the double-stranded palindromic region (two copies of 117) formed by self-annealing of the guide polynucleotides, the type Ils restriction enzyme is able to, characteristic to its activity, cleave single-stranded locations (130, 135) distal to its binding site (FIG. 15B). One of these cleavable single- stranded locations (135) is on the nucleic acid strand (101) that comprises the target nucleic acid sequence (101). The other cleavable single-stranded location (130) is located on the guide polynucleotide itself (130). If selective enzymatic conditions, an engineered polymerase, or BspD6I is used, cleavage at one of the sites (e.g. the single-stranded site on the nucleic acid strand (101) that comprises the target nucleic acid sequence (101)) can be favored. Cleavage at the single-stranded site on the nucleic acid strand (101) that comprises the target nucleic acid sequence (101) generates a free 3' hydroxyl that can then be extended by a strand-displacing polymerase present in the reaction.
[00333] The DTECT method described herein can continue in a third stage with the process depicted in FIG. 15D through FIG. 15F. Extension of the free 3' hydroxyl by the stranddisplacing polymerase (140, FIG. 15C) produces a region (160) of the nucleic acid strand (101) that comprises the target nucleic acid sequence (101) that is complementary to the restriction endonuclease recognition sequence for the type Ils restriction enzyme (117) from the guide polynucleotide (FIG. 15D). Extension of the nucleic acid (100) displaces the second copy of the guide polynucleotide (116/117, lower molecule), that previously formed half of the guide complex. Extension of the nucleic acid (100) with the region complementary to the restriction WSGR Docket No. 52459-726.601 endonuclease recognition sequence for the type Ils restriction enzyme (160) forms a new double-stranded structure where a type Ils restriction enzyme (120) can bind (FIG. 15E). As in the second stage, the type Ils restriction enzyme is able to cleave single-stranded locations (130, 135) distal to its binding site (FIG. 15E). While cleavage at the single-stranded site (135) that contains the target nucleic acid site (100) causes the strand (100) to merely be extended again by the polymerase, cleavage at the single-stranded site (130) allows for a new procedure to commence (FIG. 15E). Specifically, cleavage at site 130 of FIG. 15E on the annealed guide polynucleotide removes the sequence containing the blocked 3' end (116) and allows the guide polynucleotide to be extended to comprise a sequence (170) complementary to the strand (100) containing the target nucleic acid site (101) (FIG. 15F).
[00334] The DTECT method described herein can continue in a fourth stage with the process depicted in FIG. 15G and FIG. 15H. As the double-stranded structure of FIG. 15G no longer comprises a blocked 3' end, repeated cleavage at site 130 of FIG. 15G liberates a single strand comprising a sequence (170) complementary to the strand (100) containing the target nucleic acid site (101), and then allows extension of a new strand (171) to replace it. Additionally, the liberated strand (170) can further serve as a new template analogously to the strand 100 of FIG. 15A (FIG. 151), which allows for strand 170 to be further cleaved and repeatedly extended as in FIG. 15H (FIG. 15J). FIG. 15K depicts an exemplary completed extension on the new guide molecule.
[00335] In some cases, the method can continue, as seen in FIG. 15L, wherein endonucleolytic activity can occur on the second complementary strand oligo/extension product complex (170). FIG. 15M depicts a polymerase (140) extending of the 3’ end of the cut site of the second complementary strand of the oligo/extension product complex. Endolytic activity on the newly synthesized strand (130) occurs (FIG. 15N) and the displaced, single-stranded synthesized fragment (42) of FIG. 150 can serve as starting material for additional strand displacement amplification reactions.
[00336] In some cases, methods according to the disclosure do not involve amplification and utilize the structure depicted in FIG. 15A to direct cleavage of a single-stranded nucleic acid molecule (100) containing a target site (101) at a specified position (135, FIG. 15B).
[00337] The DTECT amplification methods described herein can utilize DNA polymerases with high strand-displacement activity and specially designed primer sets to exponentially amplify a target sequence. The combination of the DTECT amplification methods with the sample processing, stabilizing, and/or amplifying compositions described herein may provide a faster WSGR Docket No. 52459-726.601 time to amplify a target nucleic acid molecule compared to a time with an existing amplification and/or sample processing method. The DTECT method can comprise contacting a singlestranded nucleic acid molecule with a guide complex comprising a guide polynucleotide under conditions where the guide polynucleotide hybridizes to the single- stranded nucleic acid molecule, wherein the guide polynucleotide comprises: (i) a non-target binding region comprising a restriction endonuclease recognition sequence for an enzyme (e.g., a restriction enzyme). The restriction enzyme can be a type Ils restriction enzyme. The guide polynucleotide can further comprise (ii) a target binding region configured to hybridize to the target sequence. The guide polynucleotide can further comprise (iii) a blocked 3' end non-extendable by a polymerase. In some embodiments, the guide polynucleotide further comprises (i), (ii), and (iii) in 5' to 3' order. The non-target binding region can be located at the 5' end of the guide polynucleotide. The target binding region can be located at the 3' end of the guide polynucleotide. In some embodiments, the non-target binding region further comprises a sequence containing a reverse complement of the restriction endonuclease recognition sequence for the type Ils restriction enzyme 3' to the restriction endonuclease recognition sequence for a type Ils restriction enzyme and 5' to the target binding region configured to hybridize to the target sequence. In some embodiments, in (b) the cut exposes an extendable 3' end of the target sequence. In some embodiments, the method further comprises reverse-transcribing the singlestranded nucleic acid molecule from an RNA. The nucleic acid target processed (e.g., nicked or cut mediated by the guide complex or enzyme) by the methods described herein may be used as an initial template to be used with any existing isothermal amplification.
[00338] The isothermal amplifications can be performed at a constant temperature, for example, at about 45°C, about 46°C, about 47°C, about 48°C, about 49°C, about 50°C, about 51°C, about 52°C, about 53°C, about 54°C, about 55°C, about 56°C, about 57°C, about 58°C, about 59°C, about 60°C, about 61 °C, about 62°C, about 63 °C, about 64°C, about 65 °C, about 66°C, about 67°C, about 68°C, about 69°C, about 70°C, about 71 °C, about 72°C, about 73°C, about 74°C, about 75°C, about 76°C, about 77°C, about 78°C, about 79°C, or about 80°C.
[00339] Amplification products of any amplification reactions described herein can be detected by various methods. The amplification products may be detected by gel electrophoresis, thus detecting reaction products having a specific length. The nucleotides may, for example, be labeled, such as, for example, with biotin. Biotin-labeled amplified sequences may be captured using avidin bound to a signal generating enzyme, for example, peroxidase. Nucleic acid detection methods may employ the use of dyes that specifically stain double-stranded DNA. WSGR Docket No. 52459-726.601
Intercalating dyes that exhibit enhanced fluorescence upon binding to DNA or RNA can be used. Dyes may be, for example, DNA or RNA intercalating fluorophores and may include but are not limited to the following examples: Acridine orange, ethidium bromide, Hoechst dyes, PicoGreen, propidium iodide, SYBRI (an asymmetrical cyanine dye), SYBRII, TOTO (a thiaxole orange dimer) and YOYO (an oxazole yellow dimer), and the like. Dyes can provide an opportunity for increasing the sensitivity of nucleic acid detection when used in conjunction with various detection methods and may have varying optimal usage parameters. Nucleic acid detection methods may also employ the use of labeled nucleotides incorporated directly into the target sequence or into probes containing complementary or substantially complementary sequences to the target of interest. Such labels may be radioactive and/or fluorescent in nature. Labeled nucleotides, which can be detected but otherwise function as native nucleotides, can be to be distinguished from modified nucleotides, which do not function as native nucleotides. The production or presence of target nucleic acids and nucleic acid sequences may be detected and monitored by Molecular Beacons. The production or presence of target nucleic acids and nucleic acid sequences may also be detected and monitored by Fluorescence resonance energy transfer (FRET).

[00374] The excipient contained Tris, potassium phosphate, sodium chloride, ethylenediaminetetraacetic acid (EDTA), potassium chloride, dithiothreitol (DTT), nonoxynol-9, trehalose, dextran, polysucrose 400, and a cyclodextrin.

[00375] The recovery buffer used in this Example included cyclodextrin, EDTA, polysorbate 80, magnesium sulfate (MgSCU), sodium sulfate (NaSCU), ammonium sulfate (NH4SO4), and Tris (Tris 2A:8B). The concentrations of the reagents of the recovery buffer can vary.

The results of the experiment are shown in FIGs. 9-11. For each figure, amplification was assessed for different samples between cucurbit[7]urils alone (CCB; shown in column 1 in Table 10), cucurbit[7]urils with gamma-cyclodextrin (CCB+gamma; shown in column 2 in Table 10), and gammacyclodextrin alone (gamma; shown in column 3 in Table 10). Amplification was quantified by cycle threshold, wherein the number of reaction cycles to reach “positive” threshold is the cycle threshold (Ct) value. The lower the Ct value (meaning, the fewer cycles needed to turn a test positive), the greater the amount of genetic material is present in the original sample. All three gene targets were from the human gene sequence. The amplification program was 58°C for 15 minutes with data collection performed approximately every 12 seconds.
[00376] As shown in FIG. 9, when tested with 18s RNA sample from PAX tube, the combination of cucurbit[7]urils with gamma-cyclodextrin showed an improvement compared in cycle threshold, compared to that from cucurbit[7]urils alone and gamma-cyclodextrin alone. FIG. 10 shows amplification results using a IL1RN RNA sample. Cucurbit[7]urils alone (CCB) showed improvement in amplification compared to that of gamma-cyclodextrin alone and cucurbit[7]urils with gamma-cyclodextrin. The combination of cucurbit[7]urils with gamma- cyclodextrin showed a small improvement over gamma-cyclodextrin alone. As shown in FIG. 11, the three experimental conditions were also tested with MCTP1 sample. Cucurbit[7]urils WSGR Docket No. 52459-726.601 alone (CCB) showed improvement in amplification compared to that of gamma-cyclodextrin alone, and a small improvement compared to the amplification of MCTP1 following cucurbit[7]urils with gamma-cyclodextrin. FIG. 12 shows a summary of the three experiments, from left to right: 18s RNA, IL1RN RNA, and MCTP1 RNA. For each gene target, the bars from left to right denote: CCB alone, cucurbit[7]urils and gamma-cyclodextrin, and gamma- cyclodextrin alone. The results showed that for later amplifying targets (e.g., IL1RN), the addition of the cucurbit[7]uril tended to help with the amplification of low prevalence RNAs. These later amplifying targets can refer to those gene targets that have a higher number for the cycle threshold. Overall, the addition of cucurbit[7]urils was advantageous for the amplification of some gene gargets when attempting to amplify directly from PAX samples.
Example 9. Tris titration in DTECT amplification reactions
[00377] An experiment was conducted to assess how different Tris concentrations in the recovery buffer may affect amplification in a multiplex reaction (as quantified by cycle threshold). The concentration of Tris in the recovery buffer (700 mM) was diluted to 175 mM, 157 mM, 140 mM, 122.5 mM, 105 mM, 87.5 mM, 70 mM, 52.5 mM, 35 mM, and 17.5 mM (FIG. 13) for final concentrations in the reaction. It was hypothesized that increased buffering capacity may mitigate potential risk from challenging or unknown sample matrices. A human RNase P assay within the sexually transmitted infection (STI) tetraplex panel was performed using the range of titrated Tris concentrations and purified human control RNA (commercial source, Life Technologies) was used as template. The amplification program was 58 °C, and the recovery buffer contained components as described herein. The amounts and/or concentrations of all other components was kept constant with the only alteration being the Tris concentration. [00378] Reagents and concentrations for the Tris titration experimental setup of this Example are shown in Table 12.

[00379] The excipient contained Tris, potassium phosphate, sodium chloride, ethylenediaminetetraacetic acid (EDTA), potassium chloride, dithiothreitol (DTT), nonoxynol-9, trehalose, dextran, polysucrose 400, and a cyclodextrin. The concentrations of each component in the excipient can vary. Tris was present in the presence of the sample at a concentration of about 0.002 molar (M) to 0.1 M; sodium chloride and/or potassium chloride was present in the presence of the sample at a concentration of about 0.01 M to 0.3 M; DTT was present in the presence of the sample at a concentration of about 0.001 M to 0.02 M; EDTA was present in the presence of the sample at a concentration of about 0.01 mM to 0.1 mM; nonoxynol-9 was present in the presence of the sample at a concentration of about 0.05% v/v to 0.5% v/v; trehalose was present in the presence of the sample at a concentration of about 0.01 M to 0.5 M; dextran was present in the presence of the sample at a concentration of about 0.5% w/v to 5% w/v; poly sucrose 400 was present in the presence of the sample at a concentration of about 0.08% w/v to 1.0% w/v; and cyclodextrin was present in the presence of the sample at a concentration of about 0.01 M to 0.5 M.
[00380] As shown in FIG. 13, the amplification reactions can tolerate high concentrations of Tris and can function at various Tris concentrations. The results show that decreasing Tris concentrations (e.g., final concentration in amplification reaction) resulted in decreasing cycle threshold (Ct) values. Concentrations of 35 mM, 52.5 mM, and 17.5 mM showed the lowest Ct values compared to other tested Tris concentrations. WSGR Docket No. 52459-726.601

Example 11. Effects of different cyclodextrin species in DTECT chemistry
[00385] A series of experiments was performed to examine the effects of adding in additional cyclodextrin (e.g., hydroxypropyl beta cyclodextrin and methyl beta cyclodextrin) in the recovery buffer used in examples 1-5 on the amplification reactions. Assay was performed using PAX whole blood sample (e.g., blood sample collected from PAX tube). Cq values were compared between samples run with the recovery buffer (denoted as “standard recovery” for the buffer used in examples 1-5), samples run with recovery buffer with additional (2- hydroxypropyl) P-cyclodextrin, and samples run with recovery buffer with additional methyl-P- cyclodextrin. The standard recovery buffer contained (2-hydroxypropyl) P-cyclodextrin and (2- hydroxypropyl) y-cyclodextrin. The results of the amplification reaction are shown in Table 14. Samples were processed over 4 repetitions.
