METHODSChromatin from chicken erythrocytes was prepared by digesting nuclei to-1% acid solubility with micrococcal nuclease in 100 mM KCI, 50 mM Tris-HCl (pH 8.0), 1 mM CaC12. The reaction was stopped by addition of EDTA to 5 mM and the reaction mixture cooled to ice temperature. Nuclei were lysed and chromatin extracted in various ways (3). Wellcharacterized chromatin fractions were obtained by sedimentation on a sucrose gradient at 40C, in 25 mM NaCl, 5 mM Tris-HCI (pH 8.0), 0.1 mM EDTA. The solubility of the chromatin fractions was studied in NaCl, in mixtures of NaCl and MgC12, and in a variety of other divalent cations (6).
