TOOLS Taq DNA Polymerase is a recombinant 94 kDa DNA polymerase expressed in an E.coli strain that carries the cloned Thermu aquaticus DNA Polymerase gene. It possesses both 5’-3’ polymerase and exonuclease activity, and has no detectable 3’-5’ exonuclease activity. The extension rate of TOOLS Taq DNA Polymerase is 1-2 kb/min in PCR. In addition, it has a 3’ adenylation activity. Thus, the PCR products can be used directly in TA-cloning procedures.
