Abstract

DNase I pretreatment of 16S rRNA gene PCR reagents was tested. The DNase I requirement for the elimination of false-positive results varied between 0.1 and 70 IU per master mix depending on the applied Taq polymerase. PCR sensitivity was mostly maintained when 0.1 IU of DNase I was used.

摘要

对16S rRNA基因PCR试剂进行了DNase I预处理测试。根据所使用的Taq聚合酶不同,消除假阳性结果所需的DNase I量在每个反应预混液0.1至70 IU之间变化。当使用0.1 IU的DNase I时,PCR灵敏度大多能得以维持。
