title: Histones of Xenopus laevis erythrocytes. Purification and characterization of the lysine-rich fractions.
abstract: Lysine-rich histones have been isolated from the terminally differentiated erythrocytes of Xenopus laevis. Three major proteins have been separated by ion-exchange chromatography. These proteins have been characterized by electrophoresis, amino acid analysis and immunochemical techniques. It is concluded that two 'typical' lysine-rich subfractions are present in Xenopus erythrocytes and, in addition, a serine-rich histone, that shares no common antigenic determinants with the other lysine-rich histones.
