Originally isolated from the thermophilic archaebacteria Pyrococcus woesei. Pwo DNA Polymerase exhibits high levels of 3‘→5‘ exonuclease (proofreading) activity and 5‘→3‘ processivity for use when high levels of PCR accuracy are essential. It also exhibits very high thermal stability and will generate PCR products without overhanging ends, making it suitable for ‘blunt end’ cloning experiments.
