title: Separation of Friend erythroleukaemic cell histones and high-mobility-group proteins by reversed-phase high-performance liquid chromatography.
abstract: A procedure for the rapid separation of histones and high-mobility-group (HMG) proteins from Friend erythroleukaemic cells (line F4N) by reversed-phase high-performance liquid chromatography is reported. By using a Nucleosil 300-5 C4 column and a multistep water-acetonitrile gradient containing 0.1% trifluoroacetic acid, the HMG-1 and HMG-2 proteins, several H1 subfractions including H1(0), H4, H2B, two H2A variants and two H3 subfractions were separated. Under changed conditions, by applying a varied acetonitrile gradient system, even two H2B variants were fractionated. The methods described seem to be a real alternative to the time-consuming polyacrylamide gel electrophoresis.
