A multilayer analytical element for fluorometric assay of an analyte contained in an aqueous sample liquid, utilizing a competitive binding reaction to a protein between the analyte and a fluorescent-labelled analyte substance or analogue thereof, which comprises:
a porous fibrous or non-fibrous spreading sheet containing a predetermined amount of the fluorescent-labelled analyte substance or analogue thereof;
a porous sharing sheet enabling substantial separation of a bound fluorescent-labelled complex (B) of the protein from the free fluorescent-labelled analyte substance or analogue thereof (F); and
a reaction sheet containing a predetermined amount of the protein specifically bindable to the analyte fixed therein;
being under laminated structure in this order.
A slide enclosing the multilayer analytical element and a fluorometric assay employing the multilayer analytical element are also disclosed.
