KBC Turbo Pfu Polymerase

 | Post date: 2017/05/21 | 


KBC Turbo Pfu DNA Polymerase is a recombinant form of highly thermostable DNA polymerase from the hyperthermophilic archaeum Pyrococcus furiosus which is expressed in E.Coli. The enzyme catalyzes the template-dependent polymerisation of nucleotides into duplex DNA in the 5'→3' direction. Turbo 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. Recombinant changes in enzyme make it possible to facilitate faster polymerization of Turbo Pfu versus other competitors.

The error rate of Pfu DNA Polymerase in PCR is 2.6 x 10-6 errors per nucleoid per cycle as determined by a modified method described by Lundberg et al. accordingly, the accuracy of PCR is 3.8 x 105. The Pfu DNA Polymerase has no detectable reverse transcriptase activity. dUTP, dITP, and primers containing these nucleotides should not be used in PCR with Pfu DNA Polymerase because the binding of this enzyme to DNA templates with uracil and hypoxanthine stalls DNA synthesis.

Features & Benefits:
• Eight times more accurate than Taq DNA polymerase
• Highly thermostable—remains 95% active after 2 hours incubation at 95°C
• Generates blunt-end PCR products
• Incorporates modified nucleotides (e.g., biotin-, digoxigenin-, fluorescently-labeled nucleotides)
• Increased PCR yields with Pfu DNA Polymerase

• High fidelity PCR
• Generation of PCR products for cloning and expression
• RT-PCR for cDNA cloning and expression
• Blunt-end PCR cloning
