Modification of the reactivity of reagents used in agglutionation reactions by co-coating with substances that do not bind to the analyte

摘要

Agglutination reagent for the determn. of an analyte comprises a carrier particle to which are attached 1 species of ligand (I) having binding affinity for the analyte and 1 species of ligand (II) having no affinity for the ligand, provided that the agglutination reagent is in a hypercritical state (term not defined).
