Test strip kits in immunoassays and compositions therein

摘要: An assay method and compositions are provided for determining the presence of an analyte in a sample. The is member immunological pair (mip) immunogens--ligand receptor. has two basic elements: solid surface to which one members bonded signal producing system, includes catalytic mip, system results measurable on said related amount medium. generating compound produced without separation catalyst labeled mip bound from free solution. In preferred embodiment, enzyme acts conjunction with solute produce product binds preferentially when surface, resulting readily differentiated by bulk
