Detection and quantitative analysis of a specific RNA target e.g. for gene expression analyses can be performed via Reverse Transcription (RT) followed by real-time PCR (qPCR) or end-point PCR analysis (RT-qPCR or RT-PCR, respectively). RNA is first converted into complementary DNA (cDNA) by reverse transcriptase from total RNA (10 pg to 1 µg) or poly(A)-enriched RNA (e.g. mRNA, 1 pg to 20 ng). The cDNA is subsequently used as template for (q)PCR amplification of target specific fragments.
