Taq DNA Polymerase


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

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*.

  • Note: This product is supplied with 10X reaction buffer containing 15 mM magnesium chloride. dNTP (10 mM) mixture must be ordered separately (see related products).

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


    Formulation
    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.
    Concentration:
    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.
