Reversed-phase high-performance liquid chromatography (HPLC) was employed for analysing mono- and oligo(ADP-ribosyl)ated histones. Under the chromatographic conditions described, the ADP-ribosylated histones showed similar retention times to the unmodified histones, although the molecular weight and the charge of the proteins are significantly altered by their modification. The simultaneous elution of unmodified and labelled modified histones was detected by two types of gel electrophoresis and by autoradiography. In addition, the HPLC fractions did not display overlapping ladders of the multiply modified histones, as is commonly seen in one-dimensional electrophoretic analyses of unfractionated material. Hence individual bands could be unambiguously assigned. After in vitro labelling of isolated rat liver nuclei, the following ADP-ribosylated and unmodified histones were identified by HPLC and gel electrophoresis: histone H1(0), four histone H1 subfractions, histone H2A.1, histone H2A.2, oxidized histone H2A.2, histone H2A.X, histone H2A.Z, histone H2B, three histone H3 variants and histone H4.
