Product information "Pwo proofreading DNA polymerase"

The High-Fidelity Pwo proofreading DNA polymerase from Genaxxon bioscience is a thermostable, highly processive enzyme possessing 5'-3' DNA polymerase with additional 3'-5' proofreading exonuclease activity, which enables the correction of nucleotide incorporation errors. It has no 5'→3' exonuclease activity. The High-Fidelity Pwo DNA polymerase is a recombinant form of the hyperthermophilic archaebacteria Pyrococcus woesei.

Pwo proofreading DNA polymerase shows an increased thermostability and a 10-times higher accuracy compared to Taq DNA polymerase >. A mixture of Taq DNA Polymerase and Pwo DNA polymerase provides more robust synthesis of longer amplification products (Barnes, 1994. Proc. Natl. Acad. Sci. USA 91:2216-2220).

Test sample available at a special price! The test sample price will be refunded on the first official order of the product.

The extension rate of the Pwo or Pfu is lower than that of a standard Taq (up to 4 times). Therefore, it is a common phenomenon that the bands are weaker when using Pwo or Pfu compared to a standard Taq. To obtain a higher yield of amplified DNA with Pwo or Pfu, you should increase the extension time up to twice the time you need with a standard Taq.
