Application

Taq DNA Polymerase from Thermus aquaticus has been used:
  • in the quantification of fungal growth by PCR (polymerase chain reaction) and photometric assay
  • in conventional RT(reverse transcriptase)-PCR
  • in SSR (simple sequence repeats) genotyping

Taq DNA Polymerase from Thermus aquaticus is a thermostable DNA polymerase that is used for the DNA polymerase chain reaction (PCR) in order to amplify DNA sequences.

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

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.

Unit Definition

One unit will incorporate 10 nmol of total dNTPs into acid-precipitable DNA in 30 min at 74 °C.

Protocols
Hot Start dNTPs are modified with a thermolabile protecting group at the 3’ terminus. The presence of this modification blocks nucleotide incorporation by DNA polymerase until the nucleotide protecting group is removed during a heat activation step.
