ACTaq DNA Polymerase originates from Thermus Aquaticus with molecular weight of 94KDa. ACTaq Blue 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. Additionally, it also comes with preloaded blue or red tracking and loading dye. 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 Blue Hot-Start DNA Polymerase reduces the risk of contamination, making reaction preparation at ease when carried out in room temperature.
