Here, we introduced a novel exonuclease-assisted isothermal nucleic acid amplification (Exo-NAT) utilizing the full-length Bst DNA polymerase combined with a melting curve analysis. This method achieved an ultrahigh specificity with a good detection limit (10 copies) in both singleplex and multiplex detection, which was validated by detecting three diarrhea-inducing pathogens, rotavirus A, astrovirus, and adenovirus, in 42 clinical samples.
在这里,我们介绍了一种新型的外切酶辅助等温核酸扩增(Exo-NAT)技术,该技术利用全长 Bst DNA 聚合酶结合熔解曲线分析。该方法在单重和多重检测中均具有超高的特异性和良好的检测限(10 拷贝),在 42 份临床样本中检测轮状病毒 A、星状病毒和腺病毒这三种致腹泻病原体时得到了验证。
