Quantification of Transcript Levels with Quantitative RT-PCR
关键词: quantification transcript来源: 互联网
Differential gene expression is a key factor driving phenotypic divergence. Determining when and where gene expression has diverged between organisms requires a quantitative method. While large-scale approaches such as microarrays or high-throughput mRNA sequencing can identify candidates, quantitative RT-PCR is the definitive method for confirming gene expression differences. Here, we describe the steps for performing qRT-PCR including extracting total RNA, reverse-transcribing it to make a pool of cDNA, and then quantifying relative expression of a few candidate genes using real-time or quantitative PCR.
