title: Immunospecificity of non-histone chromosomal proteins in 89Sr-induced osteogenic sarcoma (mouse).
abstract: Antibodies against non-histone chromosomal proteins for 89Sr-induced osteogenic sarcoma (mouse) were prepared by immunization of rabbits. The immunoreactivity of this antigen was then compared with those of non-histone chromosomal proteins from Ehrlich ascites tumor, normal mouse liver, and calf thymus by the method of quantitative microcomplement fixation. The non-histone chromosomal proteins of 98Sr-induced osteogenic sarcoma, fractionated by hydroxylapatite chromatography, exhibited significant affinity for the antibodies. Similar proteins from Ehrlich ascites tumor, normal mouse liver, or calf thymus were virtually inactive, indicating the tissue-specificity of 89Sr-induced osteogenic sarcoma proteins.
