Figure 3From: Deacetylation of H4-K16Ac and heterochromatin assembly in senescenceDeconvoluted mass spectra of intact core histones H4, H2B, H2A1, H2A2 and H3.1 extracted from WI-38 fibroblasts under the indicated experimental conditions. For each acetylation state of H4, unmodified, mono- and di-methylated K20 forms are visible.Back to article page
