title: Buoyant density fractionation of Drosophila melanogaster chromatin.
abstract: Buoyant density fractionation of Drosophila melanogaster chromatin utilizing low molecular weight molecules such as actinomycin-D to induce changes in buoyant density has been investigated. Fractions of chromatin containing identifiable repeated DNA sequences could be isolated using actinomycin-D as the selective agent. Protein displacement from the chromatin complex was found to be a prerequisite for the observed buoyant density changes.
