FAQ: Will Nuclease P1 degrade double stranded DNA (dsDNA)?

Although a single-strand specific nuclease (ssDNA and RNA-specific), Nuclease P1 does display some activity toward dsDNA in Nuclease P1 Reaction Buffer.

If preferentially degrading single-stranded nucleic acids (ssDNA or RNA) in the presence of double stranded DNA (dsDNA), we recommend using Nuclease P1 in 1X NEBuffer 1.1 to limit activity on dsDNA while maintaining single-strand nuclease activity.
