title: Immunological analysis of histone H2A from the slime mold Physarum polycephalum.
abstract: Specific antibodies against the histone H2A from calf thymus were generated by injecting rabbits with complexes: histone H2A-RNA with a protein to RNA ratio of 3:1. In the microcomplement fixation assay the antibodies against the histone H2A from calf thymus immuno-reacted with the histone H2A from calf thymus but not with H2A from Physarum polycephalum. The histone H2A from calf thymus therefore appears to have an immunological determinant(s) which does not exist in H2A from Physarum polycephalum.
