  "summary": "This patent describes a way to test for certain bacteria, like Mycoplasma pneumoniae, by using a special antibody that can recognize two different parts of the bacteria at once.",
  "what_it_does": "This patent explains a method for medical testing, specifically an immunoassay, to find a 'test subject' that has at least two different types of antigens. The key is using a single monoclonal antibody, or a piece of it that can bind to antigens, which is designed to recognize *both* of these antigen types. This is useful in tests like the sandwich method or immunochromatography, where the antibody might be attached to a label or a solid surface. For example, it can detect Mycoplasma pneumoniae by recognizing its P1 protein and P30 protein simultaneously.",

    "Immunoassays that do not use a monoclonal antibody or antigen-binding fragment",

  "abstract": "Disclosed is a novel method of detecting a test subject by an immunoassay, in which low sensitivity due to using a monoclonal antibody is improved in spite of using a monoclonal antibody in the immunoassay. The method of detecting a test subject is a method of detecting a test subject having two or more kinds of antigens which enable detection of said test subject, which method is performed by an immunoassay such as a sandwich method, using a monoclonal antibody or an antigen-binding fragment thereof which recognizes the two or more kinds of antigens.",
