WebMicrococcal nuclease (MNase) digestion of chromatin cuts linker DNA between neighboring nucleosomes and in this way generates mononucleosomes. The protected fragments can then be analyzed by genome-wide sequencing techniques or by quantitative PCR to obtain information about the positions of nucleosomes in the chromatin. WebMicrococcal nuclease is derived from Staphylococcus aureus and is a relatively non-specific endo-exonuclease. It is purified from a recombinant E. coli strain that digests double-stranded, single-stranded, circular and …
