  • MEASUREMENT METHOD AND MEASUREMENT REAGENT FOR ANALYTE USING IMMUNOREACTION
    Publication number: 20230025583
    Abstract: A problem to be solved by the invention is to improve the sensitivity of measurement of an analyte in a sample by a sandwich immunoassay. The sensitivity can be improved significantly in a sandwich immunoassay using a first antibody and a second antibody when one or both of the first antibody and the second antibody are a mixture of a monoclonal antibody recognizing a linear epitope and a monoclonal antibody recognizing a conformational epitope.
