Loop-mediated isothermal amplification using self-avoiding molecular recognition systems and antarctic thermal sensitive uracil-DNA-glycosylase for detection of nucleic acid with prevention of carryover contamination.
环介导等温扩增(LAMP)无需温度循环即可扩增核酸,但常因引物间二聚体、非靶杂交和携带污染导致假阳性。本文建立一种由自避免分子识别系统(SAMRS)组分和南极热敏感尿嘧啶-DNA糖基化酶(AUDG)辅助的新型LAMP方法,称为AUDG-SAMRS-LAMP。将SAMRS组分引入LAMP引物3′端可提高特异性,完全避免由非靶杂交及引物...
