Low LOD 1-Step RT-qPCR Mix CN

产品亮点

对低量RNA病毒(HCV, HIV-1, HIV-2 and HAV)和DNA病毒(HBV和细小病毒B19) 的敏感和可重复检测。

图1: 同时检测DNA和RNA病毒的敏感多重qPCR反应。使用低探测极限一步法RT-qPCR混合液对提取物的每个稀释样本进行22个重复测试,以阳性扩增的比例确定检测 率。多重反应为HAV、HBV、HCV以及一个提取对照,HIV-1、HIV-2,细小病毒B19以及一个提取对照。结果表明,低探测极限一步法RT-qPCR混合物可用于以RNA和DNA 病毒为模板的多重反应,适用于不同类型病毒的病毒载量监测。
