EpiMark Hot Start Taq DNA Polymerase is a mixture of Taq DNA Polymerase and a temperature sensitive, aptamer-based inhibitor. The inhibitor binds reversibly to the enzyme, inhibiting polymerase activity at temperatures below 45°C, but releases the enzyme during normal PCR cycling conditions. This permits assembly of reactions at room temperature. An advantage of the aptamer-based hot start mechanism is that it does not require a separate high temperature incubation step to activate the enzyme. The advanced aptamer-based hot-start activity coupled with the supplied optimized reaction buffer makes the EpiMark Hot Start Taq DNA Polymerase an excellent choice for use on bisulfite-converted DNA.
