Abstract
An immunoassay for an analyte is disclosed in which (a) sample, (b) an immobilized specific binding partner for the analyte and (c) the specific binding partner for the analyte conjugated to a detectable marker are reacted together in a single step. Competitive interference of the reagents is avoided by using reagent (c) in a slow-release form as a glaze coated on a surface in contact with the reaction liquid.
