: can anyone give me some advises for my PCR on a piece of DNA that contains
: about 70% G/C? I have a lot of troubles to make the PCR working.
: thank you very much

High G/C? No problem.

Just add 15% glycerol in your PCR master mix, it'll work. I once tried 
everything to amplify a high G/C bacterial DNA, the glycerol worked best.

The theory: glycerol can lower the anealing temperature and makes DNA 
denature easier?
