AccuPower® Pfu PCR PreMix is a lyophilized mixture of Pfu DNA polymerase, dNTPs and reaction buffer in a convenient premix format. It is a high fidelity (error rate = 1.9x10-6) enzyme that will reduce errors during DNA amplification. is a recombinant enzyme that eliminates smearing and unwanted background found in native Pfu enzymes. Pfu has an optimal activity that is higher than most other thermostable polymerases, and exhibits low activity at temperatures below 50°C. This results in higher specificity for your PCR reactions.
