E00007-1000 Taq DNA Polymerase
1000 U

The applications of Taq DNA Polymerase include the following:
  • PCR*
  • 3'A-tailing of blunt ends
  • Primer extension
  • DNA sequencing

GenScript Taq DNA Polymerase has been formulated using GenScript's proprietary technology. The enzyme can be shipped at room temperature or even 37°C for seven days without any loss of activity.
Unit Definition
One unit is defined as the amount of enzyme that can incorporates 10 nmol of dNTP into acid-insoluble material in 30 minutes 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 the reaction is performed without this buffer, then add 0.1% Triton X-100 (final concentration) to ensure high activity.
Taq is delivered 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.
