Monoclonal antibodies and vaccine development directed to human cancer-associated antigens by immunization with animal and human and with synthetic carbohydrate-carrier conjugates

Abstract

A method of producing monoclonal antibodies that bind to human cancer-associated mucin-type glycoprotein antigens comprising: (1) immunizing a host with a core structure of a mucin-type glycoprotein: (2) fusing splenocytes from said immunized host with myeloma cells to form hybridoma cells; (3) culturing said hybridoma cells on selective medium; (4) selecting hybridoma cells surviving step (3) that secrete antibody that binds to said core structure of a mucin-type glycoprotein; (5) cloning said selected hybridoma cells from step (4); (6) culturing said cloned hybridoma cells; and (7) recovering said antibody. Hybridomas and monoclonal antibodies produced by the above-described method. Methods of passive and active immunization employing the monoclonal antibodies and mucin-type glycoproteins or synthetic oligosaccharide-carrier conjugates.
