The reagent is composed of a high-purified recombinant Taq DNA polymerase and
specific monoclonal antibody which inhibits enzymatic activity of the polymerase
at room temperature. According to our tests, 1 U of polymerase keeps inactive during the
incubation with the substrate for about 0.5 hour at 55°C. Activation of the enzyme
starts automatically during the first cycle of DNA denaturation.
