[Composition of labile-bound non-histone chromatin proteins in the rooster liver after treatment with estradiol].

Preparations of chromatin and labile-bound nonhistone proteins were isolated from cockerel liver cells after treatment of birds with estradiol as well as from controls. Six protein fractions were obtained by means of column chromatography on DEAE cellulose: two of these fractions were quantitatively altered due to the hormonal effect. Electrophoretic separation of both total labile-bound nonhistone proteins and their hormone-dependent fractions showed that protein composition was altered after the estradiol treatment as compared with controls.
