Hi,
I had similar problems with a very GC rich sequence. I solved the problem 
by first designing primers with high Tms (about 80 C). I then used NEB 
Deep Vent exo- (not designed for PCR but works anyway). The reaction 
conditions were 98 C 5mins, (72 C 1min,98 C 1min)X30. This amplified the 
desired product from a gene that previously didn't want to know.

hope this helps

cheers 
nick
