Taq & KlenTaq Pols and Master Mixes (6)

Taq DNA Polymerase is a thermostable enzyme that synthesizes DNA from single-stranded templates in the presence of dNTPs and a primer. The enzyme consists of a single polypeptide with a molecular weight of 94 kDa. It has a 5´→3 DNA polymerase activity and a 5´→3´ exonuclease activity. Recombinant enzyme is purified from the cloned Thermus aquaticus DNA polymerase gene expressed in E. coli.

KlenTaq® is a Klenow-fragment analog of Taq DNA polymerase. It is a 5’-exonuclease deficient Taq polymerase (an N-terminal deletion of Taq) with improved fidelity, robust and thermostability.

KlenTaq-S is a 5’-exonuclease deficient Taq polymerase (an N-terminal deletion of Taq) with improved fidelity and thermostability, plus an extra mutation rendering the enzyme PAP function (Pyrophosphorolysis-activated polymerization). The enzyme is capable of detecting rare mutations, large heterozygous deletions, gene duplications, etc. in the presence of a large excess of wild type allele and inorganic pyrophosphate). In theory PAP can detect a single base mutation in 3x1011copies of wild type allele.

Taq and Klentaq LA® (Long Accurate) versions of the enzymes are mixtures of Taq / KlenTaq and a proof reading enzyme. They can be used to amplify a long gene target with high fidelity.

Taq DNA Polymerase is a highly thermostable DNA polymerase from the thermophilic bacterium Thermus aquaticus. The enzyme catalyzes 5'→3' synthesis of DNA, has no detectable 3'→5' exonuclease (proofreading) activity and possesses low 5'→3' exonuclease activity. In addition, Taq DNA Polymerase exhibits deoxynucleotidyl transferase activity, which frequently results in the addition of extra adenines at the 3'-end of PCR products. Recombinant Taq DNA Polymerase is the ideal tool for standard PCR of purified DNA template.

Taq LA DNA polymerase is a blend of Taq DNA polymerase and one enzyme with proofreading feature. It can be used for a longer amplicon.
