title: Immunochemical characterisation of monoclonal antibodies directed to glycophorins A and/or B.
abstract: Among sixty-nine monoclonal antibodies submitted to the workshop, 28 antibodies directed to glycophorins A and/or B but without blood group specificity were investigated by a series of methods involving agglutination, flow cytometry with CHO transfected cells expressing glycophorin A, ELISA with a carbohydrate-free peptide (residues 1-72) of glycophorin A, and immunoblotting. These MAbs were subdivided in several groups according to their specificity: N-terminal portion of GPA and GPB; N-terminal trypsin-sensitive portion of GPA; extracellular ficin-sensitive portion of GPA; intracellular domain of GPA; undetermined. Both flow cytometry with transfectant cells and ELISA with the synthetic peptide prove to be of value in order to determine subspecificities within these groups.
