Asymmetric PCR method in generation of HBV ssDNA for pyrosequencing

摘要

Objective To explore the optimal primer ratio and concentration of asymmetric polymerase chain reaction (A-PCR) in producing hepatitis B virus (HBV) single-stranded DNA (ssDNA) for pyrosequencing. Methods A-PCR was carried out to generate HBV ssDNA with forward to reverse primers of different ratios (50∶1, 100∶1) and concentrations (13.0 pmol/25μL and 0.14 pmol/25μL, 19.5 pmol/25μL and 0.21 pmol/25μL), and the product yield and quality were compared respectively. Results The forward to reverse primer ratio ...
