Abstract:
1. A flow-through assay apparatus for detecting an analyte, comprising (A) a solid-phase support onto which a capture reagent that specifically binds to the analyte has been immobilized and (B) a porous material impregnated with a labeled reagent containing a ligand that specifically binds to the analyte, wherein the porous material is contained in an adaptor that (i) is provided in an upper layer of the solid-phase support and (ii) is contacted with the solid-phase support, and wherein the porous material is configured such that (iii) the analyte and the labeled reagent are contacted and mixed within the porous material and (iv) the porous material does not cover the opening of the adaptor, whereby aggregated images are observable without removing the adaptor.
