Merck, 12032937001, FastStart™ Taq DNA Polymerase, 5 U/μl

FastStart™ Taq DNA Polymerase is a versatile enzyme that can be used in a wide variety of applications and on multiple instrument platforms. This modified, thermostable recombinant Taq DNA polymerase is inactive at temperatures below +75 °C, but is activated by a 2 to 4 minute heat activation step at +95 °C. Since it is inactive at low temperatures, FastStart™ Taq DNA Polymerase cannot elongate non-specific primer-template hybrids that may form at those temperatures. FastStart™ Taq DNA Polymerase is an ideal tool for hot start PCR, because the enzyme remains inactive during PCR set-up and prior to the initial denaturation step.
