Product description: Taq DNA Polymerase is a thermostable DNA polymerase that possesses a 5'→ 3' polymerase activity and 5'→ 3' exonuclease activity. The PCR product can be cloned directly into a T-vector (TA cloning) due to the addition of an adenosine(A) to the 3' end. The thermostable enzyme is a single polypeptide chain with a molecular weight of approximately 94kD.
