Fig. 2From: The solid and liquid states of chromatinInformation obtained from the differential centrifugation assay. In this assay, chromatin is combined with MgCl2 to the indicated value, pelleted in a microfuge for 10Â min, and A260 of the supernatant measured. Data are expressed as the fraction of the chromatin in the supernatant as a function of MgCl2 concentration. Results are shown for native 12-mer nucleosomal arrays (red points and line). Factors that shift the native curve to the left or right are indicatedBack to article page
