genomic PCR

[martin LEACH]

Hi,

when I was performing PCR on a certain single-copy gene the only way we could
pull out the amplimer was to add DMSO to the PCR reaction. I believe we tried
5-10%. Concentrations of Tween 20 and NP40 also aid in some of the tough PCR
reactions.....sorry the references are long forgotten...someone else may
remember these....they are approx 6-7 years old...
