Abstract
The invention discloses a blood collection tube for protecting and stabilizing free RNA (Ribonucleic Acid). The blood collection tube is composed of a test tube, a sealing rubber plug and a protective agent. According to the blood collection tube, after blood is collected in the tube, the tube is overturned up and down for 10 times, so that the blood is fully and uniformly mixed, and the blood is stored at room temperature. The free RNA can be protected for three days, and the blood collection tube can be used for protecting and storing the free RNA.
Description
Technical field
The present invention relates to a kind of protection and the heparin tube of the free RNA of stabilization.
Background technology
Free RNA refer to be present in it is extracellular free in the body fluid such as serum, blood plasma, bronchoalveolar lavage fluid, urine, Pleural effusions
RNA。
With the exhibition of not stopping paying out of diagnostic techniques, the effect of the RNA that dissociates is increasing.
Studies have found that, expression and body fluid middle reaches in the tumor-related gene of the patients such as lung cancer, breast cancer, melanoma
Expression from cancer-related gene RNA is closely related, and free RNA can be as tumor markers, to differentiating Malignant and benign lesions
There are preferably specificity and sensitiveness.
In Non-invasive Prenatal Diagnosis, free RNA also has the effect that can not be substituted.Free fetal rna molecule mainly comes
Placenta is come from, and is stable in the presence of in parent blood circulation, it is easy to detected.Though Fetal genetic information is obtained to can be by obtaining tire
Youngster's cell is carried out, if but obtaining the invasive of fetal cell with the tradition pre-natal diagnosis of such as amniocentesis and chorionic villi sampling etc.
Mode of operation, the risk of miscarriage for having about 1%, this is greatly narrow diagnostic area.And carried out using female blood middle reaches isolated human fetal cell
Pre-natal diagnosis, though non-invasive feature can be reached, its is cumbersome, is related to relatively costly cell enrichment process, it is impossible to general
And in clinic.But, detected using the free RNA of parent, non-invasive effect can be reached, without excessively complicated mistake
Journey, it is easy to clinic popularization, there is very big prospect.
But, substantial amounts of RNase is contained in the blood of people, free RNA is very easy to be degraded by RNase, and in blood
Free RNA concentration it is very low.Clinically, most of blood for being to be gathered using heparin tube people.
And it is current, various heparin tubes are there are on the market, most of these heparin tubes all simply play anti-hemostasis
The effect of liquid solidification, without playing a part of the free RNA of protection.And in CC, due to condition or the limit of time
System, usually cannot after blood is obtained the very first time just carry out the extraction of free RNA.Cell rupture, substantial amounts of RNase, short
Just most free RNA is degraded in short several hours, great obstacle is caused to subsequent experimental, experimental result is easy
False negative is produced, so that valuable information cannot be provided for clinic.
It is therefore, a kind of that can to protect and stablize the heparin tube of free RNA be necessary.
The content of the invention
A kind of heparin tube it is an object of the invention to prepare protection and the free RNA of stabilization, the heparin tube can not only be prevented
Blood clotting, and can protect and stablize, collect wherein free RNA.The heparin tube is by test tube, seal rubber plug and protection
Agent composition.By blood collection to Guan Zhonghou, turning upside down 10 times, it is uniform to be sufficiently mixed.At room temperature, the free RNA in blood
Can preserve 3 days, -20 DEG C to -80 DEG C can preserve for a long time.
The purpose of the present invention can be achieved through the following technical solutions:
A kind of protection and the heparin tube of the free RNA of stabilization, it is characterised in that described test tube is by the poly- to benzene two of hydrophobic property
Formic acid alcohol ester material is fabricated by, and described seal rubber plug is fabricated by by butyl rubber material.
It is a kind of protect and the free RNA of stabilization heparin tube, it is characterised in that the protective agent be by EDTA-3K, IDU,
Bestain, glycine, AEBSF, ribonucleoside complex, guanidinium isothiocyanate, magnetic bead are dissolved in DEPC according to certain ratio
Water is formulated, and wherein concentration of each component in the solution is respectively:EDTA-3K(20g-80g/L)、IDU(250-
700g/L)、bestain(0.06-0.38g/L)、glycine(15-68g/L)、AEBSF(0.01-0.34g/L), ribonucleotide
Compound(0.2ml-1ml/L), guanidinium isothiocyanate(30-100g/L), magnetic bead(0.5-4mg/ml).
Preferably, the free protectant EDTA-3K of RNA of blood of the present invention, IDU, bestain, glycine,
AEBSF, ribonucleoside complex, guanidinium isothiocyanate, the concentration of magnetic bead be respectively 40g/L, 500g/L, 0.2g/L, 35g/L,
0.162g/L、0.7ml/L、60g/L、1mg/ml。
Brief description of the drawings
Fig. 1 be whole blood sample in it is of the present invention it is a kind of protect and the heparin tube of the free RNA of stabilization in preserve 0 respectively,
1st, nucleic acid extraction is carried out after 2,3 days, the nucleic acid that extraction is obtained carries out β -- the testing result of catenin mRNA real-time fluorescence PCRs.
Fig. 2 is whole blood in conventional EDTA-Na2Nucleic acid extraction is carried out after preserving 0,1,2,3 days in heparin tube respectively, is extracted
To nucleic acid carry out β -- the testing result of catenin mRNA real-time fluorescence PCRs.
Specific implementation method
Following case study on implementation is only used for explaining the present invention, rather than the limitation present invention.
Example:
With heparin tube of the present invention and routine EDTA-Na2Heparin tube randomly selects blood sample simultaneously, and each blood sample extracts 4 pipes respectively, often
Temperature place 0 day, 1 day, 2 days, after 3 days carry out nucleic acid extraction(RNeasy Mini Kit (the 50)-article No. of Qiagen companies
74104 kits), enter pedestrian β by sample of the nucleic acid of extraction -- the real-time PCR detection of catenin mRNA genes.
Testing result:
It is placed in conventional EDTA-Na2Whole blood sample in the heparin tube of heparin tube and the free RNA of protection of the present invention, normal
Temperature place different time after, nucleic acid extraction is carried out respectively, the nucleic acid of extraction enters pedestrian β -- catenin mRNA genes it is real-time glimmering
Light PCR detections, the Ct values such as table 1 of its testing result.
Table 1
As shown in Table 1, the heparin tube of the free RNA of protection of the present invention can effectively protect free RNA in 3 days, only
There is extremely slight degraded;And routine EDTA-Na2Heparin tube to the stability maintenance time of RNA less than 1 day and degraded situation ratio
It is more serious.
Fig. 1 ~ Fig. 2 is the corresponding people β of table 1 -- the real-time PCR detection result figure of catenin mRNA genes, wherein scheming
1 carries out nucleic acid extraction for whole blood is placed in the heparin tube of protection free nucleic acid RNA as herein described after preservation different time, extracts
The nucleic acid for obtaining carries out β -- the testing result figure of catenin mRNA gene real-time fluorescence PCRs, as seen from the figure, in the inspection of 0 ~ 3 day
In the survey time, all detection samples are all correctly detected, and are had good stability, and free RNA is effectively protected;Fig. 2 is
Whole blood is placed in conventional EDTA-Na2Nucleic acid extraction is carried out after different time is preserved in heparin tube, the nucleic acid that extraction is obtained carries out β --
The testing result figure of catenin mRNA gene real-time fluorescence PCRs, testing result shows, conventional EDTA-Na2Trip in heparin tube
Can not all be maintained from the RNA stability of 1 day, degraded situation is extremely serious.
The heparin tube of the free RNA of protection of the present invention is a kind of heparin tube that can efficiently protect free RNA.
