  • Protocol for Dephosphorylation of 5´-ends of DNA using rSAP (M0371)

    Protocols.io also provides an interactive version of this protocol where you can discover and share optimizations with the research community. 

    1. Prepare a 20 μl reaction as follows:
      DNA 1 pmol of DNA ends*
      CutSmart® Buffer (10X) 2 µl
      rSAP 1 unit
      H2O, purified to 20 µl**

    2. Incubate at 37°C for 30 minutes.

    3. Stop reaction by heat-inactivation at 65°C for 5 minutes.
    *Note: 1 pmol of DNA ends is about 1 µg of a 3 kb plasmid.

    **Scale larger reaction volumes proportionally.
