Taq DNA Polymerase

EC Number

  • EC


  • Taq DNA polymerase is the most widely used thermostable DNA polymerase derived from the thermophilic bacteria Thermus aquaticus (Taq ) YT-1. The enzyme possesses a 5’→3’ polymerase activity and a double-strand specific 5’→3’ exonuclease activity.

Key Specifications

Enzyme Specification:

  • Concentration/Activity*: 5U/µL
  • Purity: ≥90%
  • Endonuclease Activity: None detected
  • Nicking Activity: None detected

*One unit is defined as the amount of enzyme that will incorporate 10 nmoles of dNTP into an acid insoluble material in 30 minutes at 75°C.

Hot Start Antibody Specification:

  • Source: Mouse Hybridoma
  • Concentration: 1mg/mL
  • Inhibition Activity**: ≥95%
  • Mouse Genomic DNA Contamination: None detected

**Percentage (%) of DNA polymerase activity suppressed when 1 µG is added to 5 units of Taq DNA Polymerase at 40°C

Key Characteristics

  • Tolerates various kinds of PCR protocols
  • Applicable for hot start technology by adding anti-Taq antibody
  • PCR products can be cloned by using a TA cloning method
  • Incorporates dUTP, dITP, and fluorescently-labelled nucleotides
