Description
Taq DNA Polymerase is isolated and purified from E Coli cloned with Thermu aquaticus DNA Polymerase gene after induction table. Its molecular weight is 94 KD. Taq DNA Polymerase has 5'-3' DNA polymerase activity and 5'-3' exonuclease activity, but no 3'-5' exonuclease activity. In the PCR reaction, the extension speed of Taq DNA Polymerase is 1-2kb/min, and the product with A at the 3'end, which can be directly used for T/A vector cloning
