Pfu DNA Polymerase(-dNTPs), Economy


Pyrococcus furiosus DNA polymerase (Pfu DNA polymerase) gene was expressed in E.Coli in large quantities and highly purified. The enzyme has thermostable DNA polymerase activity and 3’ →5’ exonuclease (proofreading) activity. The MW is 90 kDa, same as that of the natural Pfu DNA polymerase.

■ Pfu DNA polymerase is thermostabe and has low error rates.
■ It is suitable for PCR and primer extension reactions that require high fidelity synthesis.
■ Pfu DNA polymerase-generated PCR fragments are blunt-ended.


1) cloning
2) DNA expression
3) site-directed mutagenesis
