    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 16 hours the percent converted to the nicked form is determined by agarose gel electrophoresis.
    • RNase Activity (16 Hour Digestion):

      The product is tested in a reaction containing a RNA substrate.  After incubation for 16 hours there is no detectable degradation of the RNA substrate as determined by gel electrophoresis.

    Notes
