Abstract
A hydratable or hydrated gel medium for use in bioassay of a test substance contains fixed in a localized zone a reagent for the test substance. Assays are conducted rapidly by diffusing the test substance followed by an indicator substance also reactive with the reagent into the zone and measuring a change in characteristics within the zone caused by the reaction of the indicator substance.
Claims11
A medium for use in bioassay diffusion processes with test substances, said medium comprising a layer of dry material hydratable to a gel through which said test substance can diiffuse, and fixed to a restricted localized zone of said layer against diffusive movement therethrough a reagent capable of reaction with said test substance, said reagent being confined to said zone which is smaller than said layer.
