Abstract
A method for immoassay includes a membrane coated with a capture antibody and starch. A solution suspected of containing an antigen is passed through the membrane. Antigen binds to the capture antibody. A conjugate of a detection antibody and lactoperoxidase is passed through the membrane to form a sandwich on the membrane. A substrate composition including peroxide and iodide is passed through. The lactoperoxidase catalyzes oxidation of iodide by the peroxide to give iodine which reacts with the starch to give a blue color. The invention includes a kit of materials for performing the assay of the invention.
