  • Immunoassay with chromatographic medium and labelled reagent
    Patent number: 4666863
    Abstract: A method of performing an assay for an analyte comprises providing a chromatographic medium, preferably in sheet form, forming a reaction mixture containing a labelled reagent present partly in a form which is mobile on the medium and partly in a form which is immobile, the proportions of the two forms being related to the analyte concentration, applying the mixture to a spot on the chromatographic medium, optionally applying a solvent to cause the mobile form of the labelled reagent to migrate from the spot, and measuring the label intensity remaining at the spot. The method provides a convenient way of performing immunoassays, 2-site immunometric assays, and agglutination assays.
