Eleven mouse monoclonal antibodies directed against epitopes on CNBr peptides of the major sialoglycoconjugate of the human red blood cell, glycophorin A, have been produced by hybridomas derived from P3-X63-Ag8.653 myeloma cells and spleen cells from BALB/c mice immunized with purified glycophorin. The monoclonal antibodies could be divided into four groups according to their reactivities with CNBr peptides in a direct ELISA assay: one antibody (6B5) that binds solely to the aminoterminal octapeptide (CNBr3); two antibodies (8F10 and 9C3) that bind to CNBrl (residues 9-81); two antibodies (3D2 and 4C6) that are reactive with CNBr2, The C-terminal portion of the molecule (residues 82-131); six antibodies (1B4, 4C3, 4E7, 7B10, 7C11 and 9D6) which are cross-reactive with an epitope on both CNBr1 and CNBR3 glycopeptides. This cross-reactive epitope(s) appears to involve both carbohydrate and protein residues.
