Micrococcal Nuclease Digestion of Schizosaccharomyces pombe Chromatin.
Digestion of chromatin with micrococcal nuclease (MNase) is widely used to probe nucleosome organization. Analysis of MNase digests by end-labeling techniques or overlapping quantitative polymerase chain reaction (qPCR) can be used to map locus-specific nucleosome positions. Furthermore, the application of genomic technologies can provide genome-wide views of nucleosome position and occupancy. This protocol provides a basic method for MNase digestion of Schizosaccharomyces pombe chromatin and depends on the production of permeabilized spheroplasts.
