Agglutination assay method in binder medium

摘要

An agglutination assay method for quantitatively determination of an analyte in a liquid sample using particles bearing an anti-analyte. The agglutination is conducted in a reagent layer composed of at least one binder selected from the group consisting of: a water-soluble polymer having a solution viscosity of 6 cP or less; a water-insoluble and water-swellable polymer; and gelatin having a molecular weight of 20,000 or less. A speedy quantitative determination of the analyte can be conveniently attained with high sensitivity. When the particle-labeled anti-analyte is contained in the reagent layer medium, the anti-analyte can be stored with higher stability in the dry state. A dry analysis element for enabling such analysis method is also provided.
