Hamster liver chromatin immunospecific non-histone proteins.
Three antisera were prepared against non-histone protein classes named NHCP1, NHCP2 and dehistonized chromatin (with different affinity to DNA) from hamster liver. Two main antigenic bands of MW 17,000 and 36,000 were specific in the NHCP1 fraction and one antigen of MW 56,000 was specific for the NHCP2 fraction from nuclease-sensitive and especially nuclease-resistant chromatin. Other NHCP2 liver antigens of MW 22,000, 27,000, 30,000, 36,000, 37,000, 40,000, 45,000, 46,000, 51,000, 98,000 and 100,000 were present only in nuclease-resistant chromatin of hamster liver. Immunologically specific hamster liver non-histone proteins within the NHCP1 and NHCP2 fractions seem to be restricted to nuclease-resistant chromatin fraction of this tissue. The above mentioned liver specific antigens are absent or present only at trace amounts in analogous Kirkman-Robbins hepatoma fractions.
