临床实验室对商品定量试剂盒分析性能的验证.pdf(17431.6k)
两个意义不一样啊,定性是确定你抗体是阴还是阳的,如果阳证明2个情况,一个是你感染了丙肝病毒,另一个是你曾经感染过这个病毒,现在已经好了。但是到底是哪个情况还要进一步做定量测试既病毒RNA检测。如果这个测试值在最低线以下就证明你现在没事,不具有传染性也不是患者只是携带者;如果高于最低线那你就是患者了,就需要治疗
1.模板提取(一般为RNA):Trizol、氯仿、异丙醇、无水乙醇、DEPC处理水
2.模板浓度测定:分光光度计或NanoDrop
3.逆转录:逆转录试剂盒(或者一步法试剂盒),这一步可以用普通PCR做,也可以用水域做。
4.荧光定量PCR试剂:通常有用SYBR Green Mix做的,但是这里建议你用EvaGreen做,灵敏度和平行性都要好于SYBR Green,并且如果你那是ABI或者Stratagene的PCR如果用SYBR Green还需要加一步Rox很麻烦。
5.其他:除了以上的那些还需要离心管、PCR管或板(Axygen反应比较好)、移液枪等,暂时就想到这么多。

只要引物设计的可以在基因组上做,那么理论上是没问题的!
只需要用RT-PCR荧光定量试剂盒里面的第二个,专门用来做Real-timePCR的那些试剂就可以了!
