Differential priming of RNA templates during cDNA synthesis markedly affects both accuracy and reproducibility of quantitative competitive reverse-transcriptase PCR.

cDNA yield did not increase with higher concentrations of specific hexamers. Higher yields with random hexamers. No data for reverse-transcription without primers.
