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...

作者报道了一种基于环介导等温扩增(LAMP)并引入南极热敏感尿嘧啶-DNA糖基化酶(AUDG)的核酸检测方案,可同时实现核酸检测与消除携带污染。该方法采用侧流层析(LFA)格式,无需标记引物或探针,可避免两条标记引物之间或标记引物与探针之间非特异杂交导致的假阳性。LAMP扩增与AUDG消化在同一管中完成,并通过封闭管反应降低携带污染...
