Abstract

We developed a two-step isothermal amplification assay system, which achieved the detection of norovirus (NoV) genomes in oysters with a sensitivity similar to that of reverse transcription-seminested PCR. The time taken for the amplification of NoV genomes from RNA extracts was shortened to about 3 h.

摘要

我们开发了一种两步等温扩增检测系统,该系统能够检测牡蛎中的诺如病毒(NoV)基因组,其灵敏度与逆转录半巢式PCR相似。从RNA提取物中扩增NoV基因组所需的时间缩短至约3小时。
