Thermo Scientific Micrococcal Nuclease (S7 Nuclease) is an endo-exonuclease that digests single-stranded and double-stranded DNA and RNA.
Micrococcal Nuclease (S7 Nuclease) is a relatively nonspecific endo-exonuclease that digests single-stranded and double-stranded nucleic acids, but is more active on single-stranded substrates. Cleavage of DNA or RNA occurs preferentially at AT or AU-rich regions, yielding mononucleotides and oligonucleotides with terminal 3'-phosphates. The enzyme's activity is strictly dependent on Ca2+.
Applications

• Hydrolysis of nucleic acids in crude cell-free extracts
• Sequencing of RNA (see​ Reference 2)
• Studies of chromatin structure
• A model for protein folding and for structure-function studies
