John J Oprandy: Membrane based dot immunoassay and method of use. The United States of America represented by The Secretary of the Navy, A David Spevack, William C Garvert, Thomas J Flanagan, April 6, 1993: US05200312 (21 worldwide citation)

Antigens or antibodies are detected using a novel membrane based immunoassay. Known antigens or antibodies which will form complexes with antigens/antibodies to be assayed are spot filtered with pressure through a membrane. The membrane, either by itself or attached to a base material as a test stri ...
