Abstract
Reverse transcription coupled with the polymerase chain reaction (RT-PCR), permits amplification of cellular RNA. Gene expression can be measured even when the message copy number is very low (1–10 copies per cell) (1) or the sample size is very small (1–1000 cells) (2,3). In RT-PCR, an RNA sample is primed with gene-specific primers, oligo dT, or random primers, and copied into a complementary DNA sequence, or cDNA, using a retroviral reverse transcriptase. The first-strand cDNA from the RT amplification of cellular RNA. Gene expression can be measured even when the message copy number is very low (1–10 copies per cell) (1) or the sample size is very small (1–1000 cells) (2,3). In RT-PCR, an RNA sample is primed with gene-specific primers, oligo dT, or random primers, and copied into a complementary DNA sequence, or cDNA, using a retroviral reverse transcriptase. The first-strand cDNA from the RT reaction is subsequently amplified using gene-specific primers and a thermostable DNA polymerase (e.g., Taq polymerase).
