Abstract: | Lymphocytes obtained from hilar and bronchial lymph nodes from 23 patients undergoing radical surgery for carcinoma of the bronchus were fused with established rat or mouse myeloma lines. 62% of the resultant hybrids were found to be secreting human Ig detected by a sensitive staphylococcal Protein A-coupled SRBC assay. Immunoglobulins synthesized by such hybrids were internally labelled with 3H-lysine and their antibody activity against a variety of membrane preparations determined. Nine monoclonal antibodies were found which bound to molecules on lung-cancer membranes and not on normal lung membranes from the same patient. |
