    Therminator γ (gamma) DNA Polymerase is a 9°N™ DNA polymerase variant with an enhanced ability to incorporate gamma-phosphate labeled dNTPs.

    Product Source

    Therminator γ DNA Polymerase is purified from a strain of E. coli that carries the 9°N (D141A / E143A / W355A / L408W / R460A / Q461S / K464E / D480V / R484W / A485L) DNA Polymerase gene, a genetically engineered form of the native DNA polymerase from Thermococcus species 9°N-7. Developed by LI-COR® Biosciences and derived from Therminator.

    Quality Control

    Quality Control Assays

    The following Quality Control Tests are performed on each new lot and meet the specifications designated for the product. Individual lot data can be found on the Product Summary Sheet/Datacard or Manual which can be found in the Supporting Documents section of this page.
    • Endonuclease Activity (Nicking):
      The product is tested in a reaction containing a supercoiled DNA substrate. After incubation for 4 hours the percent converted to the nicked form is determined by agarose gel electrophoresis.
    • Exonuclease Activity (Radioactivity Release):
      The product is tested in a reaction containing a radiolabeled mixture of single and double-stranded DNA. After incubation for 4 hours the exonuclease activity is determined by the % release of radioactive nucleotides.
