I'm supposed to be using Pfu to PCR-up some genomic DNA. I've used it before, it works... most of the time. Has anyone had problems with the enzyme dying on them? I'd like to think that my last dozen PCRs haven't worked because I'm incompetent, not the enzyme... but it hasn't worked for the other assistants in the lab either.
Is there another alternative that's more reliable?

I never touch Pfu - having been mentally scarred by it. It just didnt happen for me. I changed to another high fidelity enzyme and it worked first time - no errors.
I think it was Bioline's bio x-act that worked in the end. PWO polymerase is also good.

Another factor is that Pfu works slower than Taq, but as you used it already sucessfully I suppose that this was already considered.
