Supplied with 10X reaction buffer containing 15 mM magnesium chloride. dNTP (10 mM) mixture need to be ordered separately.
Description: Taq DNA Polymerase is a thermostable DNA Polymerase isolated from an E. coli strain that carries the Taq DNA polymerase gene. Taq DNA Polymerase is the most common polymerase used for PCR* reactions.

Applications: Taq DNA Polymerase can be used in most applications including the following:

  • PCR*.
  • 3"A-tailing of blunt ends.
  • Primer extension
  • DNA sequencing.

Formulation: Genscript Taq DNA Polymerase has been formulated using a proprietary technology, and the enzyme can be shipped at room temperature or stand at 37枫C for 7 days without losing any activity.

  • Terminal transferase activity. Taq DNA Polymerase has terminal transferase activity which results in the addition of a single nucleotide (adenosine) at 3" end of the extension product.
  • High-purity. No contamination activity has been detected in standard test reactions.

QC Tests: PCR* performance, activity, nuclease.

Unit Definition: 1 unit of enzyme incorporates 10 nmol of dNTP into acid-insoluble material in 30 min at 74°C.

10 X reaction Buffer (with Mg2+): 500 mM KCl, 100 mM Tris HCl (pH 9.0 at 25°C), 15 mM MgCl2, 1% Triton X-100 Buffer. This buffer is optimized for use with 200 µM dNTPs.

Note: If not using this buffer, 0.1% Triton X-100 (final concentration) is a must to ensure high activity.

Storage Buffer and Concentration: Supplied in 5 units/µl in 20 mM Tris HCl (pH 8.0), 0.1 mM EDTA, 1 mM DTT, 0.1% Triton X-100 and 50% glycerol.

Storage: -20°C
