title: Purification by preparative electrophoresis and characterization of histone H2B from rat chloroleukaemia.
abstract: Highly purified histone H2B from rat chloroleukaemia has been isolated by preparative electrophoresis at pH 2.7 in polyacrylamide slab gel, using the fraction F2b of Johns (Johns E. W. (1964) Biochem, J. 92, 55-59) as starting material. This histone was characterized by amino acid analysis and end groups determination. Comparative studies with homologous calf thymus histone show similarity of the amino acid compositions and of the amino terminal groups. the carboxyl terminal sequence presents two conservative substitutions.
