Methylation-sensitive single-molecule analysis of chromatin structure.
Methylation-sensitive single-molecule analysis of chromatin structure is a high-resolution method for studying nucleosome positioning. As described in this unit, this method allows for the analysis of the chromatin structure of unmethylated CpG islands or in vitro-remodeled nucleosomes by treatment with the CpG-specific DNA methyltransferase SssI (M.SssI), followed by bisulfite sequencing of individual progeny DNA molecules. Unlike nuclease-based approaches, this method allows each molecule to be viewed as an individual entity instead of an average population.
