Patent No: 5,747,048 titled ‘Monoclonal antibodies and vaccine development directed to human cancer-associated antigens by immunization with animal and human mucin and with synthetic carbohydrate-carrier conjugates’ with the 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.
Patent No: 5,660,834 titled ‘Monoclonal antibodies and vaccine development directed to human cancer-associated antigens by immunization with carbohydrate-carrier conjugates’ with the abstract : A vaccine and method to prevent growth and replication of cancer cells that express a core structure of a mucin-type glycoprotein is disclosed. The vaccine comprises: (a) a pharmaceutically effective amount of an antigen comprising a purified mucin-type glycoprotein or a chemically synthesized mucin-type glycoprotein carbohydrate determinant conjugated to a carrier peptide or macromolecule, wherein said mucin-type glycoprotein expresses or carries the core structure of a mucin-type glycoprotein expressed on said cancer cells; and (b) a pharmaceutically acceptable carrier including natural or synthetic adjuvants. The method comprises administering the above-described vaccine to a host. A medicament and method for treating cancer wherein the cancer cells express a core structure of a mucin-type glycoprotein is disclosed. The medicament comprises: (a) a pharmaceutically effective amount of an anti-cancer antibody or fragment comprising a binding site thereof, said anti-cancer antibody having been produced against a purified core structure of a mucin-type glycoprotein; and (b) a pharmaceutically acceptable carrier, diluent or excipient. The method comprises administering the above-described medicament to a host.
Patent No : 5,229,289 titled ‘Monoclonal antibodies and vaccine development directed to human cancer-associated antigens by immunization with animal and human and with synthetic carbohydrate-carrier conjugates’ with the 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.
