DNA polymerases

General use: use Phusion because of it's fidelity (and high yield) for proofreading and DyNAzyme II for other amplifications. Phusion can also be used for mutagenesis.

Extensor should only be used for really long amplicons. Extensor is not a proofreading enzyme and very expensive!!
