[Nuclear chromatin proteins of hematopoietic cells normally and in leukemia in rats].

By methods of analytical electrophoresis nuclear chromatin proteins of normal and leukaemic hemopoietic rat cells were studied. There were revealed 1--2 extra bands in the histones extracted from chromatin of leukaemic cells. These proteins appear to be identical to histones of H10 type. The majority of nonhistone proteins of nuclear chromatin from normal and leukaemic hemopoietic cells show similar electrophoretic characteristics, whereas there were also found components typical for chromatin of only normal or leukaemic hemopoietic cells.
