Product Information

Taq DNA Polymerase is a thermostable DNA polymerase that has 5´→ 3´ polymerase activity and 5´ flap endonuclease activity. Edna Taq products are recombinantly produced in E. coli and thus are highly pure and offer robust and reliable PCR activity.

What's In The Box:

The product includes a vial of the formulated recombinant enzyme along with 10X Taq reaction buffer which is detergent-free and designed to be compatible with existing assay systems.


  • Isolated from a recombinant source

  • The enzyme is free of any tags

  • Supplied with 10X Reaction Buffer

  • Robust and reliable reactions

  • Tolerates a wide range of templates

  • Incorporates dUTP, dITP and fluorescently-labeled nucleotides

  • An ideal tool for amplifying DNA of length <5 kb

Product Source

An E. coli strain that carries the Taq DNA Polymerase gene from Thermus aquaticus.
