Abstract:
A dry analysis element for quantitatively determining an analyte in an aqueous liquid sample by measuring the extent of agglutination of particles bearing an anti-analyte, the anti-analyte being capable of specific binding to the analyte the agglutination of said particles being caused by a binding reaction between the analyte and the anti-analyte on the particles, comprising:a non-fluid medium layer composed of a non-fluid substance which retains said particles bearing the anti-analyte therein while suppressing the diffusion of said particles; and a water permeable layer which is superimposed on said non-fluid medium layer and contains a solation agent being capable of increasing the fluidity of the non-fluid substance; whereby, when the sample is applied to the water permeable layer, said solation agent transfers to the non-fluid medium layer from the water-permeable layer together with the sample and increases the fluidity of said non-fluid substance to accelerate the agglutination of the particles in the non-fluid medium layer if the analyte is present in the sample.
