  • Protocol for Dephosphorylation of 5´-ends of DNA using CIP (M0290)

    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
      CIP 1 unit
      H2O, purified to 20 μl**

    2. Incubate at 37°C for 30 minutes.

    3. Purify DNA by gel purification, spin-column or
      phenol extraction.

    * Note: 1 pmol of DNA ends is about 1 μg of a 3 kb plasmid.
    ** Scale larger reaction volumes proportionally.
