HELP! VENT / Pfu amplification

Although some optimization was necessary, the yield of DNA (0.14 
to 2.3 kb frags) from amplification using Pfu is now comparable to 
that obtained with taq. I reduced my Mg++ by 2/3, added 1/10 vol of 
DMSO and reduced the dNTPs to 1/5 of that in a reaction using taq. 

I have also reduced the cycle number from 30 to 25 and raised the 
annealing temperature in most cases to 62C.

Hope this advice helps

Andrew
