The PCR fidelity assay was carried out7,10 except that the lacIOlacZa target was amplified from the same cDNA synthesis reaction mixture using different PCR enzymes. For cDNA synthesis, MMLV-RT was used essentially as described in the ProSTAR Ultra HF RT-PCR system protocol using in vitro transcribed RNA.
