Abstract
The present invention is directed to in vitro and in vivo immunodiagnosis and immunotherapy using monoclonal antibodies reactive with difucosyl blood group antigens Y-6 and B-7-2.
Claims6
An in vitro method of screening to aid in the diagnosis of adenocarcinoma by detecting the presence of difucosyl blood group antigens Y-6 and B-7-2 expressed by adenocarcinoma which comprises contacting a sample with a diagnostically effective amount of detectably labeled monoclonal antibody which binds to the same epitope as the monoclonal antibody produced by a cell line selected from the group consisting of ATCC HB 9324 and ATCC HB 9347 and determining the binding of said monoclonal antibody with said antigens wherein the presence of said binding is indicative of the presence of adenocarcinoma expressing said antigens.
An in vivo method of screening to aid in the diagnosis of adenocarcinoma by detecting the presence of difucosyl blood group antigens Y-6 and B-7-2 expressed by adenocarcinoma which comprises administering to an individual a diagnostically effective amount of detectably labeled monoclonal antibody which binds to the same epitope as the monoclonal antibody produced by a cell line selected from the group consisting of ATCC HB 9324 and ATCC HB 9347 and determining the binding of said monoclonal antibody with said antigens wherein the presence of said binding is indicative of the presence of adenocarcinoma expressing said antigens.
