我做的病毒的普通PCR结果还可以。我现在要做该病毒的定量。用的是ICycler定量PCR仪器。有那位高手能告诉我怎样操作该仪器。
我还要重新设计目的基因片段的因物吗?如果不用重新设计,那我下一步应该为做定量PCR做哪些准备呐?还需要设计参照模板吗?
这种实验的把握性有多大?
大家有什么更好的建议吗?
什么是纯荧光校正,多长时间校正一次:
纯荧光校正是测定各种纯荧光染料标准品的波长和信号强度,通俗地说是让仪器“认识”各种荧光染料。软件收集并储存各种纯荧光染料标准品的荧光信息。以后每次定量实验运行过程中,SDS软件收集样品的原始光谱信号,并将此原始光谱与纯荧光文件中的数据进行比较,精确扣除不同染料的信号重叠部分,从而确定样品中的荧光染料种类和信号强度。
推荐每半年进行一次纯荧光校正。在运行光谱校正之前,请先进行背景校正和ROI校正。
这些染料的结构式基本是保密的。有些地方能查到,象维基上就有SYBR Green的结果式,但谁也不能肯定是否是正确的。
1.怎么看两个反应-即目标基因和内参基因是否具有相同的扩增效率?
2.每次PCR反应的扩增情况都有差异,多次反应的扩增效率岂不是都不一样了吗?
3.如何设计才能让相对定量更可行?
由于对定量PCR的接触不多,希望各位高手多多帮助!谢谢!
