Abstract excerpt
Chromatin can be analysed by assaying its sensitivity to DNase I or other nucleases in purified nuclei. Usually, this is performed by Southern analysis of genomic DNA extracted from nuclease-treated nuclei, a methodology that requires many cells. Applying restriction fragment length polymorphisms (RFLPs), this methodology has been used for parental allele-specific chromatin studies on imprinted mammalian genes....
