Description

Description:
Pfu DNA Polymerase is a highly thermostable DNA polymerase from hyperthermophilic archaeum Pyrococcus furiosus. The enzyme catalyzes the template-dependent polymerization of nucleotides into duplex DNA in 5′->3′ direction. Pfu DNA Polymerase also exhibits 3′->5′ exonuclease (proofreading) activity, that enables the polymerase to correct nucleotide incorporation errors. It has no 5′->3′ exonuclease activity. The main difference between Pfu and alternative enzymes is that Pfu has superior thermostability and proof-reading properties. Unlike Taq DNA polymerase, Pfu DNA polymerase also possesses 3′->5′ exonuclease proofreading activity, resulting in PCR fragments with fewer errors than Taq-generated PCR inserts. Pfu DNA polymerase is efficient for techniques that require high-fidelity DNA synthesis, but can also be used in conjunction with Taq polymerase to obtain the fidelity of Pfu with the speed of Taq polymerase activity.

Applications:

  • High-fidelity PCR and primer-extension reactions
  • Generation of PCR products for cloning and expression
  • PCR cloning and blunt-end amplification product generation
  • RT-PCR for cDNA cloning and expression
  • Site-directed mutagenesis
  • Blunt-end PCR cloning
