Identification of single-nucleotide polymorphisms by the oligonucleotide ligation reaction: a DNA biosensor for simultaneous visual detection of both alleles.

Analytical chemistry 2009 Toubanaki DK, Christopoulos TK, Ioannou PC, Flordellis CS

单核苷酸多态性(SNP)虽可用等位基因特异性寡核苷酸直接杂交识别,但酶法基因分型具有更高特异性和稳健性。在酶法中,寡核苷酸连接反应(OLR)因连接需两个杂交事件而具有最高等位基因判别能力。本文报道一种 DNA 生物传感器,用于同时视觉检测两种等位基因,并显著优于现有 OLR 产物检测方法。该传感器仅需一次连接反应,数分钟内完成,无需...

已知单核苷酸多态性(SNP)基因分型多基于等位基因特异性探针杂交、寡核苷酸连接反应(OLR)、引物延伸或侵入性切割。OLR 因涉及两个识别事件而具有更高特异性:等位基因特异性探针与通用探针在靶 DNA 相邻位点杂交,连接酶仅在完全互补时连接。连接产物可用比色、时间分辨荧光、化学发光、电泳、微阵列、微球或均相荧光/比色法检测。本文开发...
