This 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 40 °C, but releases the enzyme during normal PCR cycling conditions. Advantages: Reduction of primer dimers. No inactivation time. Avoid non-specific bands. More stable than antibody based Hot-start taqs. More economical than antibody based Hot-start taqs.
