Taq Polymerase Standard (5u/ull)


SKU: P03-CR103S Category:


Taq DNA Polymerase is a highly thermostable DNA polymerase of a thermophilic bacterium Thermus aquaticus. Taq DNA Polymerase catalyzes 5’=>3′ synthesis of DNA. The enzyme has no detectable 3’=>5′ proofreading exonuclease activity and possesses low 5’=>3′ exonuclease activity. This enzyme adds a single 3′-A overhang to each end of the PCR product, which can be applied to T/A cloning. The recombinant Taq DNA Polymerase is ideal for standard PCR of templates 5 kb or shorter.
