A study of histone-histone interactions by affinity chromatography
Mol Biol Rep.
1976 Sep.
Abstract
Homologous whole histone from calf thymus was adsorbed on Sepharose 4B columns with covalently coupled histone fractions H2a, H2b, H3 or H4 in 0.01 M phosphate buffer, pH 6.7 - 1 M NaCl. The adsorbed histones were eluted from the columns with 5 M urea in the same buffer. Electrophoretic analysis has shown that the different columns exhibit selective affinity to the histone fractions: the H2b column to histone H2b and H2a (with only weak affinity to histones H3 and H4), the H2a column to histones H2b and H3 (moderate affinity to histone H2b), and the H4 column to histone H3, H4 and H2b (weak affinity to histone H2a). Histone H1 displayed no fixation by either of the columns tested.
