    Quality Control

    Quality Assurance Statement

    • 5-methyl-dCTP is certified free of nucleases and phosphatases.
    • The purity of dATP is ≥ 99% as determined by HPLC analysis.

    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.
    • Functional Test (Methylated dNTP):
      The methylated dNTP and the appropriate non-methylated dNTP are tested in a polymerase chain reaction (PCR).  The fragments from each reaction are digested with 5mC methyl sensitive enzymes and electrophoresed on an agarose gel. The methylated dNTP product falied to cut by these enzymes, whereas the dCTP product was digested by both enzymes.
