ACTaq™ DNA Polymerase originates from Thermus Aquaticus with molecular weight of 94KDa. ACTaq™ Hot-Start DNA Polymerase differs from ACTaq™ DNA Polymerase such that it contains antibody binding Taq which enables the activation of Taq only at 95oC. The activation step eliminates the presence of non-specifics such as primer-dimer formation and mis-primed products, by ensuring the enzyme is inactive at temperature below 95oC. ACTaq™ Hot-Start DNA Polymerase reduces risk of contamination, making reaction preparation at ease when carried out in room temperature.
