General description

Taq DNA Polymerase is a thermostable enzyme derived from the thermophilic bacterium Thermus aquaticus. The enzyme is in a recombinant form, expressed in E. coli. It can withstand repeated heating to 95 °C without significant loss of activity. Each lot of Taq DNA Polymerase is tested for PCR amplification and double-stranded sequencing.

Application

Taq DNA Polymerase from Thermus aquaticus has been used:
  • in the quantification of fungal growth by polymerase chain reaction (PCR) and photometric assay
  • in conventional reverse transcriptase (RT)-PCR
  • in simple sequence repeats (SSR) genotyping
  • as a component of PCR mix for amplification of genomic and mitochondrial DNA
  • in direct tetra-primer amplification refractory mutation system (T-ARMS) PCR to amplify dried whole blood samples

Biochem/physiol Actions

Taq polymerase catalyzes oligonucleotide primer-driven, DNA template dependent incorporation of dNTPs into complimentary DNA strands. It displays both 5′ to 3′ polymerase and exonuclease activities.

Features and Benefits

  • Low per unit cost of Taq

Packaging

Taq DNA Polymerase with 10× reaction buffer containing MgCl2
Taq DNA polymerase comes with the choice of an optimized 10× reaction buffer including MgCl2 (D1806) or a 10× reaction buffer without MgCl2 plus a separate tube of MgCl2 for titration (D4545). The latter option may be necessary to determine optimal conditions for amplification.

Other Notes

One unit will incorporate 10 nmol of total dNTPs into acid-precipitable DNA in 30 min at 74 °C.
Taq DNA Polymerase is a specialized thermostable enzyme isolated from the thermophilic bacterium Thermus aquaticus. The recombinant form of this enzyme is expressed in E. coli. This 94 kDa protein shows no detectable levels of contaminating endonucleases or exonucleases by SDS-PAGE. It has both 5′→3′ polymerase and exonuclease activity.
