Pfu DNA Polymerase 2x master mix is ready to use premix which contains Pfu DNA Polymerase, dNTPs, MgCl2 and stabilizers with optimized reaction buffer. It has been optimized for routine PCR applications. Pfu DNA Polymerase is a heat stable DNA polymerase which has 5´→ 3´ DNA polymerase and 3´→ 5´ exonuclease (proofreading) activities. Pfu DNA polymerase retains the high fidelity, sensitivity and processivity with an error rate six-fold lower than Taq DNA polymerase, and significantly lower than the error rates of most other proofreading enzymes or DNA polymerase mixtures (1). Pfu 2x Master Mix product is supplied with the unique Intact Genomics 5x Magic Enhancer that enables efficient amplification of GC rich templates up to 84%.
