title: Characterization of monoclonal antibodies directed against erythrocytic stage antigens of Plasmodium berghei.
abstract: Monoclonal antibodies recognizing various facets of the malaria parasite Plasmodium berghei and of the infected erythrocyte were obtained after generation of hybridomas between spleen cells from immunized mice and myeloma cells. The monoclonal antibodies were characterized by enzyme-linked immunosorbent assay, indirect immunofluorescence, immunoprecipitation of [35S]methionine-labeled proteins and immunoblotting. The most readily identified antigen was a parasite surface-associated protein of 230 kDa which is similar to the polymorphic schizont antigen described in a number of malarial species. In addition, three distinct antigens of 13, 31 and 120 kDa, which are external to the parasite, but within the infected erythrocyte were identified.
