An immunochemical assay device comprising a base member, an array disposed on the base member, and at least one assay indicia zone. The array comprises (i) a reservoir pad to receive sample liquid, (ii) a wicking membrane, and (iii) at least one filter zone interposed between the wicking membrane and the reservoir pad. The filter zone being operable to permit passage of any specific immunocomplex to the wicking membrane while impeding passage of larger components.

An immunochemical label comprising finely particulate carbon black on which is adsorptively immobilized a component which terminates distally from a point of adsorption with an immunologically active ligand or ligand binding molecule wherein said component comprises said immunological ligand or ligand binding molecules covalently linked through a linking reagent, and said linking reagent is adsorbed on the surface of said carbon black.

An immunoassay reagent is disclosed comprised of carbon black and ligands which are coupled to the carbon black through a linking agent, together with a device comprised of the immunoassay reagent.

Specific binding labels are described which comprise carbon black treated with dextran to which various specific binding reagents are bound by way of fluorescein isothiocyanate.
