  • Detection of haptoglobin for gastrointestinal cancer determination
    Patent number: 11579146
    Abstract: The invention provides gastroenterological cancer determination methods that involve contacting a specimen, an antibody 1 that recognizes an ? chain of human haptoglobin, and an antibody 2 that recognizes a ? chain of human haptoglobin and does not recognize human haptoglobin in which an S—S bond is cleaved to form a complex 1, or contacting the specimen and two antibodies selected from the antibodies 2 that recognize a ? chain of human haptoglobin and do not recognize human haptoglobin in which an S—S bond is cleaved to form a complex 2. A determination is made based on the measurement of complex 1 or 2. Alternatively, the specimen and two antibodies selected from the antibodies 1 that recognize an ? chain of human haptoglobin are contacted to form a complex 3, and a determination is made by comparing the measurement results of complex 1 or 2 with complex 3.
