Multilayer analysis element utilizing specific binding reaction.

摘要

A dry type multilayer analysis element for assaying a concentration of a specific component utilizing a competitive immune reaction comprises a detection element comprising a detection layer which receives a labelled complex formed as a result of the competitive immune reaction or an optically detectable change formed dependant upon an amount of the labelled complex of the specific component and having further provided thereon the detection layer a reaction layer comprising a fibrous porous medium. The multilayer analysis element absorbs an amount of a sample solution necessary for the competitive immune reaction so that the multilayer analysis element has high sensitivity and high reproducibility.
