A procedure for in vitro sensitization of human lymphocytes against bombesin conjugated to tetanus toxoid (BTT) is described. Bombesin is a tetradecapeptide associated with small cell lung carcinoma. We found that antibody responses against bombesin as well as tetanus toxoid could be generated in vitro by culturing nylon-separated human splenic lymphocytes for 6 days with lipopolysaccharide, phytohemagglutinin-activated lymphocyte supernatants, human AB serum, and bombesin conjugated to tetanus toxoid. Cells sensitized by this procedure were fused to murine myeloma cells, NS-1. The specificities of resulting hybrids were analyzed by enzyme-linked immunoassays and competitive inhibition experiments. Hybrids secreting anti-bombesin (IgM) or anti-tetanus toxoid (IgM or IgG) were obtained. The ratio of IgG to IgM antibodies against tetanus toxoid could be increased by using antigen coupled to Sepharose beads. The sensitization procedure described here offers a system for the study of antigenic stimulation of human B lymphocytes in vitro and for the production of human monoclonal antibodies with the desired specificities.
