High GC PCR

[jeremy m vanderweele]

I'm having a lot of difficulty amplifying a high GC (82-90%) region using
the GC-melt kit from Clontech.  The region is also pretty repetitive,
which makes it difficult to get good primers.  Does anyone have a better
protocol to PCR high GC regions?  (Cheaper would also be nice--Clontech's
enzyme costs a fortune.)

Thanks,
