Claims (15)
1. System til selektiv detektering af en målnukleotidsekvens, hvilket system omfatter mindst ét sonde:antisondesystem, der omfatter; (a) et sondeoligonukleotid, der omfatter en nukleotidsekvens, der er komplementær til en første målnukleotidsekvens, og en første markørdel forbundet dermed; og (b) et antisondeoligonukleotid, der omfatter en nukleotidsekvens fuldt komplementær til sondeoligonukleotidet bortset fra mindst én fejlmatchet base i en ikke-terminal position, og en anden markørdel, hvor den anden markørdel er bundet til antisondeoligonukleotidet eller er et område af antisondeoligonukleotidet, hvor: (i) sondeoligonukleotidet er konfigureret til større hybridiseringsaffinitet for den første målnukleotidsekvens end for antisondeoligonukleotidet; og antisondeoligonukleotidet er konfigureret til større hybridiseringsaffinitet for sondeoligonukleotidet end sondeoligonukleotidet har hybridiseringsaffinitet for en anden målnukleotidsekvens af interesse; (ii) i tilstedeværelse af den første målnukleotidsekvens, sondeoligonukleotidet og den første målnukleotidsekvens danner et dupleks, hvorefter første og anden markørdele ikke interagerer, hvorved der tilvejebringes et første detekterbart signal; (iii) i fravær af den første målnukleotidsekvens, sondeoligonukleotidet og antisondeoligonukleotidet danner et dupleks, hvorved det gøres muligt for første og anden markørdele at interagere for at tilvejebringe et moduleret detekterbart signal, hvor det første og de modulerede detekterbare signaler kan adskilles fra hinanden; og (iv) i tilstedeværelse af den anden målnukleotidsekvens, der adskiller sig fra den første målsekvens med mindst en basefejlmatch, sondeoligonukleotidet og antisondeoligonukleotidet fortrinsvis danner et dupleks, hvorved sondeoligonukleotidet hæmmes i at danne et dupleks med den anden målnukleotidsekvens.
2. System ifølge krav 1, hvor duplekset af sondeoligonukleotidet og den første målnukleotidsekvens, og duplekset af sondeoligonukleotidet og antisondeoligonukleotidet adskiller sig med mindst ca. 2 kcal/mol i AG og mindst ca. 4 °C i Tm; og hvor duplekset af sondeoligonukleotidet og den anden målnukleotidsekvens, og duplekset af sondeoligonukleotidet og den første målnukleotidsekvens adskiller sig med mindst ca. 4 kcal/mol i AG og mindst ca. 8 °C i Tm.
3. System ifølge krav 1, hvor sondeoligonukleotidsekvensen er konfigureret med en fejlmatchet baseposition ca. to baser væk fra et forventet fejlmatch mellem den anden målnukleotidsekvens og sondens sekvens; hvorved de to fejlmatchede baser genererer et indre ikke-hybridiseret to- eller tre-base-område af sondeoligonukleotid: anden målnukleotidsekvenskomplekset, hvilket dupleks derved har AG og Tm, der er mindre end AG og Tm for sondeoligonukleotid:antisondeoligonukleotidduplekset.
4. System ifølge krav 1 til 3, hvor én markørdel er en fluorescens-emitter, og den anden markørdel omfatter en fluorescens-modulator; hvor fluorescens-modulatoren er valgt fra gruppen bestående af: en quencher-forbindelse, en fluorescerende forbindelse, en metalpartikel og et guanin-rigt konjugat.
