Detection of nucleic acids and elimination of carryover contamination by using loop-mediated isothermal amplification and antarctic thermal sensitive uracil-DNA-glycosylase in a lateral flow biosensor: application to the detection of Streptococcus pneumoniae.

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...
