I think that advantage is a 1/50 ratio of a bit of proofreading enzyme and
normal Taq with a bit of Taq start Ab. I know that they use Advantage in
their ddRT-PCR Delta kit and you can sometimes get a spurious banding
pattern. (don't know the reason but this may be it)
You could use PFU from Stratagene. I beleive that is more accurate WRT
mutation rate. It is a bit pricey but so is a failed reasction or over
I could dig out a reference for you WRT enzyme mutation rates but I am in
the middle of transferring from Endnote to !Citation and then BibTex for a
Give me a private e-mail if you have no sucess here and I'll have a hunt
at the weekend.
