Product description: pfu DNA Polymerase is a recombinant thermostable enzyme from Pyrococcus furiosus, expressed in Escherichia coli. It catalyzes the polymerization of nucleotides into duplex DNA in the 5'→3' direction and exhibits 3'→5' exonuclease activity in the presence of Mg2+, can correct the wrong DNA amplification base. The error rates of pfu DNA Polymerase is the lowest, is just 1.3x10-6. pfu DNA Polymerase is recommended for use in PCR and primer extension reactions that require high fidelity.
