Pfu DNA polymerase (+dNTPs), Economy, with reaction buffer

Cat. No. 02-021
Store at -20°C
size 200 Units / 5X 200 Units


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. 


2.5 units/ul, where one unit is defined as the amount of enzyme that can incorporate 10 nmols of dNTPs into an acid-insoluble material in 30 minutes at 72℃ when activated salmon sperm DNA was used as template/primer.

Quality Assurance

Greater than 95% of protein determined by SDS-PAGE (CBB staining) (Fig.1) The absence of endonucleases and exonucleases was confirmed.

PCR Test

Good amplification result was obtained in PCR reaction using λDNA as a template (Fig.2). 

Reagents Supplied with Enzyme

10 x Reaction Buffer (Pfu): 200mM Tris-HCl (pH 8.8), 100mM KCl, 100mM (NH4)2SO4, 20mM MgSO4, 1% TritonX-100, 1 mg/ml BSA
 2.5mM (each) dNTPs
