A panel of hybridoma lines were produced by the fusion of Sp2/0 myeloma cells and spleen cells from mice immunized with pig peripheral blood lymphocytes. Thirty-three stable hybridomas were produced which secreted monoclonal antibodies that reacted with pig lymphocytes, as determined by an ELISA screening procedure. These monoclonal antibodies were characterized by a complement-mediated cytotoxicity test and by flow cytometric analysis. The molecular weights of the antigens recognized by the monoclonal antibodies were determined by immunoprecipitation of /sup 125/I surface labeled lymphocytes, followed by SDS-PAGE. One monoclonal antibody, 7-34-1 (IgG2a), which reacted to all peripheral blood lymphocytes, precipitated a MHC class I molecule composed of a 50 kd heavy chain and a 12 kd light chain (..beta../sub 2/ microglobulin). This monoclonal antibody may prove to be an important reagent for the detection of SLA antigens on pig cells.
