The Hot Start Taq DNA Polymerase is a recombinant Taq DNA polymerase which 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 extension of non-specifically annealed primers or primer dimers and providing higher specificity of DNA amplification. The functional activity of the enzyme need to be activated in incubation at 95°C for 10 minute. The activated enzyme maintains the same functionality.

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 3' end. The PCR product can be cloned in TA vector.
