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.

  • Note: This product IS supplied WITH 10X reaction buffer containing 15 mM magnesium chloride. dNTP (10 mM) mixture must be ordered separately
    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.
