What is the difference between native and recombinant Taq DNA polymerase?

Product FAQ

Answer

Native Taq DNA polymerase is purified from the thermophile, Thermus aquaticus YT1. Recombinant Taq DNA polymerase is expressed in E.coli and purified. This procedure separates a high molecular weight form of the enzyme (94,000 kDa) from a low molecular weight form (87,000 kDa) - recombinant Taq DNA polymerase comprises only the 94,000 kDa form. This 94,000 kDa form is much more thermostable and exhibits a small amount of 5′ to 3′ exonuclease activity. Recombinant Taq DNA polymerase and native Taq DNA polymerase are essentially identical in terms of their activity, specificity, thermostability, and performance in PCR. The recombinant Taq sequence is identical to the native sequence (this sequence is available from GenBank).

How does does Platinum® Taq DNA Polymerase differ from regular Taq Polymerase?

Product FAQ

Answer

Platinum® Taq DNA Polymerase is designed for hot-start PCR. Because it is bound by a monoclonal antibody, Platinum® Taq DNA Polymerase is inactive when the temperature is below 94 degrees C. The high-temperature step at the beginning of the PCR cycle (typically 94 degrees C) denatures and dissociates the antibody from the polymerase, restoring it to full activity.

Mispriming typically occurs at the start of PCR. Using a hot-start polymerase such as Platinum® Taq DNA Polymerase dramatically reduces mispriming, as it has little to no activity until after the denaturation step. Therefore, hot-start PCR--mediated by Platinum® Taq DNA Polymerase--has a higher specificity than PCR with standard Taq DNA Polymerase.
