  • Protocol for Dephosphorylation of 5'-ends of DNA using AnP (M0289)

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


    1. Add 1/10 volume of 10X Antarctic Phosphatase Reaction Buffer to 1-5 µg of DNA cut with any restriction endonuclease in any buffer.
    2. Add 1 µl of Antarctic Phosphatase (5 units) and mix.
    3. Incubate for 15 minutes at 37°C for 5´ extensions or blunt-ends, 60 minutes for 3´ extensions.
    4. Heat inactivate (or as required to inactivate the restriction enzyme) for 5 minutes at 70°C.
    5. Proceed with ligation.
