WebRT-PCR uses RNA as starting material for in vitro nucleic acid amplification. The discovery of retroviral reverse transcriptase in the early 1970s ultimately made RT-PCR possible. Reverse transcriptase is an RNA-dependent DNA polymerase, catalyzing DNA synthesis using RNA as the template. WebSuccessful RT-PCR also depends on RNA quantity, which may need to be varied to determine the optimal amount. Excellent amplification results can be obtained with the Access and AccessQuick™ RT-PCR Systems using total RNA template levels in the range of 1pg–1μg per reaction (Figure 3) or poly(A)+ RNA template levels in the range of …
