  • METHOD OF ASSISTING DIAGNOSIS OF INFLAMMATORY BOWEL DISEASE
    Publication number: 20230228769
    Abstract: An object of the present invention is to provide a method of assisting diagnosis of inflammatory bowel disease, which can specifically determine inflammatory bowel disease. The present invention relates to “a method of assisting diagnosis of inflammatory bowel disease, the method including subjecting a subject-derived specimen to a reduction treatment and subsequently measuring a human prohaptoglobin amount in the specimen by using an antibody 1 which is an antibody that specifically binds to an amino acid sequence set forth in SEQ ID NO: 1, and determining that a subject has inflammatory bowel disease by using the human prohaptoglobin amount as an indicator, and relates to an examination kit for assisting diagnosis of inflammatory bowel disease, including the antibody 1 a reducing agent”.

  • METHOD FOR DETERMINING PROSTATE CARCINOMA
    Publication number: 20210215699
    Abstract: The present invention relates to a method for determining prostate carcinoma, including obtaining a ratio 1 between an amount of a free prostate specific antigen and an amount of a free PSA having an ?(2,3) glycan, the free PSA having an ?(2,3) glycan being a free prostate specific antigen having a glycan in which a terminal sialic acid residue of the glycan is ?(2,3)-linked to a second galactose residue from a terminal of the glycan, in a sample derived from a subject; obtaining a ratio 2 between the ratio 1 and a volume of the prostate of the subject; and determining prostate carcinoma based on the obtained ratio 2.
