DF-Pfu DNA Polymerase is a thermostable polymerase of approximately 92 kDa isolated from the hyperthermophilic archae bacteria Pyrococcus furiosus

This enzyme replicates DNA at 75°C, catalyzing the polymerization of nucleotides into duplex DNA in the 5’ → 3’ direction in the presence of magnesium with a preference for MgSO4. DF-Pfu DNA Polymerase is free of bacterial DNA.

Unlike Taq DNA Polymerase, DF-Pfu DNA Polymerase possesses 3' to 5' exonuclease proofreading activity that enables the polymerase to correct nucleotide-misincorporation errors. Due to this feature, DF-Pfu DNA Polymerase-generated PCR fragments exhibit the lowest error rate of any thermostable DNA polymerase. This results in a 12-fold increase in fidelity of DNA synthesis compared with Taq DNA Polymerase, which has an error rate Pfu 1.3 x 10-6.
