Abstract
TAKAHASHI, N., KOIZUMI, Y., KAWAGUCHI, T., TAKAHASHI, K., SUZUKI, T. and FUNYU, T. Production of a Monoclonal Antibody Selective to Human Transitional Cell Carcinoma. Tohoku J. exp. Med., 1987, 151(2), 213-220-In order to detect the bladder tumor specific antigens, the monoclonal antibody (MoAb) No. 10 to human transitional cell carcinoma of the bladder (T.C.C.B.) was obtained. Hybridomas were prepared by cell fusion between the mouse myeloma cell line × 63 Ag 8.653 and the spleen cells of BALB/c mouse hyperimmune to the bladder cancer cells (grade 2) from a patient, and were cloned. Consequently 12 MoAb-producing clones were obtained for the panel screening by enzymeimmunoassay (EIA) and then 3 MoAbs (No. 10, 11 and 14) were selected for the testing of reactivity to bladder cancer cells from patients including normal epithelia. Finallly No. 10 was selected as the most appropriate MoAb for this study and was determined IgM with kappa-light chains by EIA.
