Thermo Scientific Native Taq DNA Polymerase is a highly thermostable DNA polymerase of the thermophilic bacterium Thermus aquaticus.
Thermo Scientific Taq DNA Polymerase, native, is a highly thermostable DNA polymerase of the thermophilic bacterium Thermus aquaticus. The enzyme catalyzes 5' to 3' synthesis of DNA, has no detectable 3' to 5' exonuclease (proofreading) activity, and possesses low 5' to 3' exonuclease activity. In addition, the polymerase exhibits deoxynucleotidyl transferase activity, which frequently results in the addition of extra adenines at the 3'-end of PCR products. Native Taq DNA Polymerase is preferred for amplification of bacterial DNA sequences homologous to those found in E. coli.
Available with or without the stabilizing agent BSA, Taq DNA Polymerase, native, with BSA, is often considered the best choice when amplifying DNA samples of lower purity, e.g., genomic DNA from mouse tail.
Both native Taq DNA polymerases are supplied with two buffers: 10X Taq Buffer with KCl and 10X Taq Buffer with (NH4)2SO4. The latter allows for PCR at a wide range of magnesium concentrations and decreases unspecific priming
