  • METHOD FOR MEASUREMENT OF EQUOL IN BIOLOGICAL SAMPLE BY IMMUNOASSAY, KIT FOR THE MEASUREMENT, AND METHOD FOR DETERMINATION OF EQUOL PRODUCTION ABILITY OF SUBJECT
    Publication number: 20120064550
    Abstract: An object of the present invention is to provide a method for measuring equol in a biological sample by an immunological method, a kit for the measurement, and a method for determining equol-producing ability of a subject. The measurement method of the present invention is characterized in that S-equol is used as at least one antigen selected from the group consisting of a standard antigen used for the preparation of a standard curve and a labeled antigen that competes with equol in a biological sample. The kit of the present invention is characterized in including S-equol as at least one antigen selected from the group consisting of the standard antigen and the labeled antigen.
