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
