The protein composition of the liver chromatin has been studied by two techniques for fractionation of histones. The "lability" fraction of histones H2A-H2B is revealed. In these fractions histones H2B have many modified forms and they are not included into octamer (H3, H4, H2A, H2B)2. Young animals rather than old ones have much quantitative subfractions of histone H2B. The "lability" fraction of histones H2A-H2B is stated to be very significant in the activated and repressed chromatin structure.
