Abstract
Disclosed is a method for measurement of an analyte in a microparticle-based analyte-specific binding assay, wherein the microparticles are coated with the first partner of a binding pair, the method involving mixing the coated microparticles, an analyte-specific binding agent conjugated to the second partner of the binding pair, and a sample suspected of containing or containing the analyte, wherein the second partner of the binding pair is bound to the analyte-specific binding agent via a linker having from 12 to 30 ethylene glycol units (PEG 12 to 30), thereby binding the analyte via the conjugated analyte-specific binding agent to the coated microparticles, 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.
