PCR yield enhancing effect of BSA as used as a co-additive with organic solvents. Typical examples of the effects of BSA as a co-additive with DMSO and formamide, at different concentrations, on PCR amplification of GC-rich DNA templates. A) Effect of DMSO on PCR of che1P (left) and combined effect of DMSO with 6 μg/μl BSA (right) as observed by gel electrophoresis of total PCR product. B) Effects of formamide on PCR amplification of che1P (left) and combined effect of formamide with 6 μg/μl BSA (right) in comparable experiments.
