The Hot Start Taq DNA Polymerase is a recombinant Taq DNA polymerase that has been chemically modified by the addition of heat-labile blocking groups to its amino acid residues. The enzyme is inactive at room temperature, avoiding the extension of non-specifically annealed primers or primer dimers and providing higher specificity of DNA amplification. The functional activity of the enzyme is activated in 10-minute incubation at 95°C. The activated enzyme maintains the same functionality as Taq DNA polymerase: Has the 5′to 3′DNA polymerase activity and 5′to 3′exonuclease activity without 3′-5′exonuclease activity. The extending speed is 1 kb/30 sec. There is an "A" on the 3′end. The PCR product can be cloned in TA vector.
