| Abstract: | Six histone H1 subtypes and histone H5, isolated from chicken erythrocyte nuclei, were visualized on acid/urea polyacrylamide gels. Four of the H1 subtypes have been purified to homogeneity by fast protein liquid chromatography on a strong cation exchange column. The other two subtypes were obtained as enriched fractions from the same fast protein liquid chromatography experiments. Because six chicken H1 genes have been completely sequenced (Coles, L.S., Robins, A. J., Madley, L.K., and Wells, J. R. E. (1987) J. Biol. Chem. 262, 9656-9663), it was possible to assign each of the six H1 proteins to a specific gene after amino acid sequence analysis of peptides derived from the subtypes. |
