  • Patent number: 11099180
    Abstract: The disclosure concerns a method and kits for measurement of an analyte in a microparticle-based analyte-specific binding assay. In the assay, the microparticles are coated with the first partner of a binding pair, mixing the coated microparticles and at least two analyte-specific binding agents, each conjugated to the second partner of the binding pair, and a sample suspected of containing the analyte. The second partner of the binding pair is bound to each of the analyte-specific binding agents via a linker comprising from 12 to 30 ethylene glycol units (PEG 12 to 30), thereby binding the analyte via the conjugated analyte-specific binding agents to the coated microparticles. The method also entails separating the microparticles having the analyte bound via the binding pair and the analyte-specific binding agent from the mixture and measuring the analyte bound to the microparticles.
