title: A monoclonal antibody (1B7) specific for polymorphic determinant on mouse I-A antigens recognizes monomorphic epitope shared by most of RT-1 haplotypes in rats.
abstract: A monoclonal antibody, 1B7, which was established by immunizing C57BL/10 mice with splenocytes from B10.BR, was investigated by serological, immunochemical and functional analyses in mouse, rat, guinea pig and human systems. 1B7 recognized a polymorphic determinant on class II antigens in the mouse system. In the rat system, however, this antibody appeared to recognize a monomorphic epitope shared by all RT-1 haplotypes. 1B7 showed no reactivity in the human and guinea pig strains tested.
