- Has anyone out there much experience with doing PCR on GC-rich
- DNA? I am having a devilishly difficult time of it. I'm trying
- to amplify three genes from a 68% G+C region from Alcaligenes
- eutrophus and none of the six primer pairs that I have tried
- have given me even fair accumulation of amplified product.
- Even 10% formamide and a 4 minute 100 degree C denaturation
- (with Vent, a more stable polymerase than Taq) did not work.
- I've extensively analyzed my primers, but I do not see how
- they could be the problem in all six cases.
- An emailed response to eschen@molbio.cbs.umn.edu would be
- appreciated. Thanks. -Art
