DNA Polymerase for PAGE Enzyme (with 2.5 mM dNTPs)

DNA Polymerase for PAGE is purified from E. coli expressing a cloned DNA polymerase from Thermus aquaticus. The enzyme consists of a single polypeptide with a molecular weight of approximately 94 kDa. DNA Polymerase for PAGE has 5′-3′ DNA polymerase activity and 5′-3′ exonuclease activity. The extension rate is about 1-2 kb/min. This enzyme is supplied with a unique buffer compatible with PAGE, and the resulting PCR product is suitable for use in SDS-PAGE and agarose gel electrophoresis. The enzyme can amplify genomic DNA fragments up to 3 kb.

For some targets, a higher Mg2+ concentration may be required. For optimal results, we recommend using a 100 mM MgSO4 stock solution to prepare a titration from 2 mM to 4 mM (final concentration) in 0.25 mM increments. 0.5 µl (2.5 U) enzyme is sufficient per 50 µl reaction volume. For better amplification, up to 1 μl (5 U) enzyme can be used.
