Hi Fred,

While you are working on the optimization of your PCR, I strongly suggest you to read our paper on partial overlapping primer design from a link below, which will surely ease your mutagenesis:

I would be happy to answer your questions should you have.

Cheers

Hi CCP4 list,
Thanks everyone who have answered my post concerning to mutagenesis.
From quick reading most of the answers, the following seems to be a consensus:
1) Do not concentrate your PCR product;
2) Too much DNA and/or impurities like salts or whatever can inhibits transformation;
3) Purify your PCR product before transformation if possible or use 3 of 4 microL of it. This is more or less the amount of DNA showed in the uploaded image.
Kind regards,
Fred

P.S.: I'll let you know the results.
