Pfu Plus DNA Polymerase is a thermostable enzyme of approximately 90kDa isolated from Pyrococcus furiosus. The enzyme replicates DNA at 75oC, catalyzing the polymerization of nucleotides into duplex DNA in the 5´-3´ direction in the presence of magnesium. Pfu DNA Polymerase also possesses 3´-5´ exonuclease (proofreading) activity. Base misinsertions that may occur during polymerization are rapidly excised by the proofreading activity of the polymerase. Consequently, Pfu DNA Polymerase is recommended for use in PCR and primer extension reactions that require high-fidelity synthesis. Pfu DNA Polymerase-generated PCR fragments are blunt-ended.
Pfu Plus DNA Polymerase exhibits the lowest error rate of any thermostable DNA polymerase.
