Taq DNA Polymerase (Native and Recombinant)

Isolated from the thermophilic bacterium Thermus aquaticus, Taq DNA polymerase is one of the best-known thermostable DNA polymerases used in PCR amplification of DNA targets. The native enzyme is purified from Thermus aquaticus YT1. The recombinant enzyme is a cloned version that is purified from E. coli. Therefore, the native Taq DNA polymerase is often preferred for amplification of bacterial DNA sequences homologous to E. coli sequences.

Find the DNA polymerase for your PCR application

Since the first report on PCR using Taq DNA polymerase, better-performing DNA polymerases are continually being developed to meet the needs of increasingly challenging research applications. The enzymes listed below help improve PCR performance in a variety of aspects such as sensitivity, specificity, accuracy, and inhibitor tolerance.
