Disclosed is a glycoprotein, CORA, which has a binding affinity for carcinoembryonic antigen (CEA). This glycoprotein is a marker for carcinoma, and can be characterized by having a molecular weight of about 46,000 - 50,000 daltons, an isoelectric point of about 3.0 - 3.5, a carbohydrate content of about 25 -35% by weight, reactivity with antisera raised thereto, and substantially no reactivity with antisera raised to nonspecific cross-reacting antigen (NCA) or to CEA. Also disclosed are a hybridoma which produces a monoclonal antibody to CORA, the monoclonal antibody to CORA, and a device, kit, and method for detecting and monitoring carcinoma. |
