|Source||Isolated from E.coli strain that carries the cloned DNA polymerase gene from Pyrococcus furiosus.|
|Description||Pfu DNA Polymerase catalyzes the DNA-dependent polymerization of nucleotides into duplex DNA in the 5` -> 3` direction in the presence of magnesium ions. The enzyme also exhibits 3` -> 5` exonuclease (proofreading) activity, that enables the polymerase to correct nucleotide incorporation errors. Products of reaction have blunt ends.|
Pfu DNA Polymerase useful for high fidelity synthesis and polishing ends.
|Unit definition||One unit of enzyme catalyzes the incorporation of 10 nanomoles of deoxyribonucleotides into a polynucleotide fraction (adsorbed on DE- 81) in 30 minutes at 72°C.
Unit Assay Conditions: 1 x Pfu DNA polymerase buffer,
0.1 mg/ml BSA, 200μg/ml activated calf thymus DNA,
