  • ANTIGEN MEASURING METHOD AND MEASURING APPARATUS
    Publication number: 20220260558
    Abstract: There is provided a method for measuring an antigen, comprising: providing a solution containing an antigen; providing a first antibody that specifically recognizes the antigen and is bound to a magnetic carrier; providing a second antibody that specifically recognizes the antigen and is modified with an oxidase; providing (a substrate liquid including) a substrate which reacts with the oxidase; allowing the first antibody to recognize the antigen; allowing the second antibody to recognize the antigen; using a magnetic field to capture an antigen-antibody complex of the antigen recognized by the first antibody and the second antibody in the magnetic field; washing the antigen-antibody complex while it is captured in the magnetic field; reacting the substrate with the antigen-antibody complex to produce hydrogen peroxide; and measuring the hydrogen peroxide.
