Monoclonal antibodies to blood group antigens on ruminant red cells
Hybridomas were made between NSI/1-Ag-4-1 mouse myeloma cells and spleen cells Balb/c mice immunized with red cells from sheep (SRBC), goats (GRBC) and cattle (CRBC). The monoclonal antibodies thus produced were tested against a panel of RBC from 80 sheep, 20 goats and 100 cattle of known blood types. One antibody reacted with all RBC from all 3 species, two with all GRBC and SRBC but not CRBC, one was specific for SRBC and two others for CRBC. In addition two monoclonal antibodies were reactive in the B blood group system and two in the FV system of cattle. IgM and IgG concentration in ascite fluids reached up to 8 mg/ml. It is concluded that the hybridoma technique has considerable potential for the production of blood-typing reagents.
