for routine high fidelity amplification of up to 3.5 kb DNA targets Cat. No. 1 664 947 100 units
Cat. No. 1 664 955 2 x 250 units Description Pwo DNA polymerase was originally isolated from hyperthermophilic archaebacterium Pyrococcus woesei. The enzyme has a molecular weight of about 90 kD. It is a highly processive 5'3' DNA polymerase and possesses an 3'5' exonuclease activity also known as proofreading activity. The enzyme has no detectable 5'3' exonuclease activity. Pwo DNA polymerase exhibits increased thermal stability with a half life of greater than 2 h at 100C compared to Taq DNA polymerase with a half life of less than 5 min at this temperature. The inherent 3'5' exonuclease proofreading activity Pwo results in an over 18-fold increased fidelity of DNA synthesis compared to Taq DNA polymerase. Pwo DNA polymerase generated PCR products are blunt-ended and can therefore be used directly for blunt-end ligation without any pretreatment of the ends.

pack insert. Application Fidelity of in vitro DNA polymerization is one of the most important subjects in PCR. For many applications of PCR, where a homogenous DNA population is analyzed (i.e. direct sequencing or restriction endonu-clease digestion), the mutations that are induced by the polymerase during PCR are of little concern. However if only a small amount of template DNA or RNA is used as starting mat
