Technically Speaking: Promega RT-PCR Systems Explained

PCR has proven to be one of the most flexible and powerful techniques in modern molecular biology. Reverse transcription-PCR (RT-PCR) adds a new dimension, coupling the conversion of RNA into complementary DNA (cDNA)by viral reverse transcriptases with the amplification of the cDNA by thermostable polymerases. Promega offers two systems for RT-PCR: The Access RT-PCR System and the Reverse Transcription System.
