title: Use of a solid-phase 3H-radioimmunoassay for the measurement of immunoglobulin produced in short-term cultures of antibody-secreting cells.
abstract: A slid-phase radioimmunoassay (RIA) for assaying immunoglobulin produced from antibody-secreting myeloma, hybridoma and immune spleen cells is described. Specific antibody is detected by culturing antibody-producing cells on antigen-coated flexible polyvinylchloride microtiter wells, washing away the cells, and measuring the bound specific antibody with tritiated affinity-purified anti-isotype reagents. Antibody produced from 10(3) myeloma cells can be detected with as little as 4 h of incubation. With 24-48 h of incubation, antibody from as few as approximately 3-15 myeloma, hybridoma or immune spleen plaque-forming cells (PFC) can be detected. This culture-well RIA has certain distinct advantages over the hemolytic PFC assay and RIA assays in which antibody in culture supernatants is measured.
