摘要
A device for performing an enzyme-labelled binding assay comprises an absorbent material and a developing solution, wherein the absorbent material is provided with a plurality of reagent zones including an indicator reagent zone, and is capable of transporting the developing solution by capillary action sequentially through each reagent zone, and wherein the indicator reagent zone includes a reagent capable, directly or indirectly, of immobilising an enzyme-labelled reagent in an amount dependent upon the assay result, characterised in that the developing solution includes a signal producing-substrate for the enzyme. The substrate moves slower through the absorbent material than the enzyme-labelled reagent or any compound of the enzyme-labelled reagent formed in the assay. The absorbent material is suitably in the form of an elongate strip provided with transverse reagent zones. The device is useful for performing immunoassays including immunometric assays and dual analyte assays of the type described in GB-B-2029011 and GB-B-2116318.
