Differential production of monoclonal antibodies to carbohydrate moiety or peptides moiety of glycoproteins by different routes of immunization.
The administration of ABO blood group active glycoproteins via the rear footpads of BALB/c mice with subsequent fusion of popliteal lymph node lymphocytes produced hybridomas differentially secreting antibodies to the peptide moiety of antigens. On the other hand, conventional intraperitoneal immunization of the same antigens and intraperitoneal boost followed by splenic lymphocyte fusion produced hybridomas differentially secreting antibodies to the carbohydrate moiety of antigens. Similar results were obtained in the production of monoclonal antibodies to erythrocyte membranes. Almost all hybridomas obtained by rear foodpad immunization secreted antibodies to the peptide moiety of erythrocyte membrane proteins, and those obtained by intraperitoneal immunization secreted antibodies to both peptide and carbohydrate moieties of erythrocyte membrane components. These results suggest the possibility of differential production of monoclonal antibodies to the carbohydrate moiety and the peptide moiety of some glycoproteins by different immunization routes.
