Label-Free Cross-Priming Amplification Coupled With Endonuclease Restriction and Nanoparticles-Based Biosensor for Simultaneous Detection of Nucleic Acids and Prevention of Carryover Contamination.
本文报道了一种无标记交叉引物扩增(CPA)方案,利用内切酶限制实现核酸的同时检测并消除携带污染。反应混合物通过纳米颗粒侧流生物传感器(LFB)进行检测。该检测无需使用标记引物或标记探针,从而避免标记引物之间或探针与标记引物之间非期望杂交导致的错误结果。等温扩增与内切酶限制消化在单管中完成,封闭管扩增可消除污染物引起的假阳性。为验证适...
