Description_x000D_ Application_x000D_ 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._x000D_ Taq DNA Polymerase from Thermus aquaticus has been used:_x000D_ • in the quantification of fungal growth by PCR (polymerase chain reaction) and photometric assay_x000D_ • in conventional RT(reverse transcriptase)-PCR_x000D_ • in SSR (simple sequence repeats) genotyping_x000D_ Biochem/physiol Actions_x000D_ 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._x000D_ Features and Benefits_x000D_ • Low per unit cost of Taq_x000D_ Packaging_x000D_ Taq DNA Polymerase with 10× reaction buffer containing MgCl2_x000D_ 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._x000D_ Other Notes_x000D_ 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._x000D_ Unit Definition_x000D_ One unit will incorporate 10 nmol of total dNTPs into acid-precipitable DNA in 30 min at 74 °C._x000D_ Legal Information_x000D_ Use of this product is covered by one or more of the following US patents and corresponding patent claims outside the US: US 8,404,464 and US 7,972,828. The purchase of this product includes a limited, non-transferable immunity from suit under the foregoing patent claims.
