Immunoassay with membrane immobilized antibody

Image Number 2 for United States Patent #4200690.

The presence of antigens is detected with a device having an antibody immunochemically reactive with the antigen bound to a first microporous membrane coated with an inert proteinaceous material and an antibody immunochemically non-reactive with the antigen bound to a second microporous membrane coated with an inert proteinaceous material. The device is particularly useful in an immunoassay for an antigen of Entamoeba histolytica in unfractionated feces or colon aspirate.
