GT-Taq DNA Polymerase
GT-Taq DNA polymerase is purified from E. coli strain carrying plasmid with the cloned gene encoding Thermus aquaticus DNA polymerase. Taq DNA polymerase catalysis 5’→3’ synthesis of DNA. The enzyme has no detectable 3’→5’ proofreading exonuclease activity but possesses 5’→3’ exonuclease activity.
