I am trying to amplify 2 kb regions in the promoters of Drosophila genes and 
need a very high fidelity enzyme. I cannot tolerate any PCR errors. I have 
tried MasterAmp Extra Long Polymerase Mix from Epicentre Technologies but it 
is encorporates too many errors. I have been trouble shooting with 
Stratagene's PfuUltra Hot Start High Fidelity enzymes but I did not find 
appropriate sized bands even after many attempts to modify annealing 
temperature, and modifying amounts of DMSO, template DNA, salts, dNTPs, 
enzyme, or primers. Does anyone recommend a very high-fidelity enzyme for 
amplification of 2kb from Drosophila genomic DNA? 

Thanks,
