Taq DNA Polymerases

Taq DNA Polymerase

Taq DNA Polymerase is commonly used for routine PCR applications in many molecular biology labs.

For your “daily” PCR we recommend NEBs reliable Taq DNA Polymerase, which is available in various Buffer- and Enzyme-formulations.

  • Isolated from a recombinant source
  • Supplied with 10X Reaction Buffer
  • Robust and reliable reactions
  • Tolerates a wide range of templates
  • Incorporates dUTP, dITP and fluorescently-labeled nucleotides
  • Exceptional value in terms of cost per unit

Hot Start Taq DNA Polymerase

Hot Start Taq DNA Polymerase is a mixture of Taq DNA Polymerase and an aptamer-based inhibitor. The inhibitor binds reversibly to the enzyme, inhibiting polymerase activity at temperatures below 45°C, but releases the enzyme during normal cycling conditions, allowing reactions to be set up at room temperature. This aptamer-based hot start does not require a separate high temperature incubation step to activate the enzyme.

NEB’s Hot Start Taq shows excellent yields while being highly specific
