Abstract:
A single-step method to dissociate histones as well as nonhistone chromosomal proteins from chicken erythrocyte chromatin and their separation into histones H1, H5, core histones, and high mobility group proteins by column chromatography on phosphocellulose is presented. NaCl at 2.0 M is effective in dissociating both histones and nonhistone proteins. The core histones elute as a complex. The pH is a critical factor in separating H5 from the core histones.
