[Immunofluorescent research on the species specificity of the antigens of hematopoietic cells in rodents].

The bone marrow cells of mice, rats, guinea pigs, Syrian and dwarf hamsters exhibit a positive immunofluorescence reaction with antisera against insoluble antigens of the bone marrow cells of mice, Syrian and dwarf hamsters and, hence, contain common "cross-reacting" antigens. The use of different methods of antiserum absorption made it possible to reveal, in addition, antigens of "narrow" specificity in (1) mice, Syrian and dwarf hamsters, (2) Syrian and dwarf hamsters, as well as species specific antigens of the bone marrow cells of mice, Syrian and dwarf hamsters.
