    FAQs

    1. Why has the buffer been changed?
    2. Is there any change to the Fragmentase enzyme?
    3. If I can’t make this change to the new buffer right now, can I still obtain the original Fragmentase buffer?
    4. What is the difference between Fragmentase Reaction Buffer (#B0348) and Fragmentase Reaction Buffer v2 (#B0349)?
    5. What other components are now included along with the dsDNA Fragmentase in M0348?

    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.
    • Non-Specific DNase Activity (16 hour, Buffer):
      The buffer is tested in a reaction containing a DNA substrate. After incubation for 16 hours there is no detectable degradation of the DNA substrate as determined by agarose gel electrophoresis.
    • Phosphatase Activity (PNPP):
      The product is tested in a reaction containing a p-nitrophenyl phosphate (PNPP), a chromogenic substrate for most phosphatases. After incubation the percent degradation is determined by spectrophotometric analysis of released p-nitrophenol at 405 nm.
    • Protease Activity (SDS-PAGE):
      The product is tested for protease activity by incubation with a standard mixture of proteins resulting in no detectable degradation of the proteins as determined by SDS-PAGE.
