 Thermo Scientific 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 templates 5 kb or shorter.

 Highlights

 ? Thermostable—half life is more than 40 min at 95°C

? Generates PCR products with 3'-dA overhangs

? Supplied with two buffers—10X Taq Buffer with KCl and 10X Taq Buffer with (NH4)2SO4. The latter allows for PCR at wide range of magnesium concentrations and decreases unspecific priming

? Incorporates modified nucleotides (e.g., biotin-, digoxigenin-, fluorescently-labeled nucleotides)

 Applications

 ? Routine PCR amplification of DNA fragments up to 5 kb

? High throughput PCR

? DNA labeling

 Note

 ? The error rate of Taq DNA Polymerase in PCR is 2.2 x 10-5 errors per nt per cycle. Accordingly, the accuracy of PCR is 4.5 x 104. Accuracy is an inverse of the error rate and shows an average number of correct nucleotides incorporated before an error occurs.

? The 10X Taq Buffer without Detergent is recommended for microarray experiments.

? Store at -20°C
