Patent DE-4120412-C1 (DE)
IPC: G01N33/573
Filed: 1991-06-20
Granted: 1993-01-07
Abstract: In order to test for the presence of antibodies (Ak), in particular auto-antibodies such as those against thyroid pro-oxidase (TPO), the invention calls for the test sample to be reacted with two other types of antibody, particularly monoclonal antibodies, and with an antigen. The two other types of antibody are an immobilized antibody (Akimm) and a suitably marked antibody (Ak*) against the antigen (Ag). The antigen is preferably used in raw, naturally occuring form, e.g. as an organ extract. The presence of the antibody (Ak) being tested for is indicated by modification of the structure of a sandwich made up of the two added antibodies (Akimm and Ak*) and the added antigen (Ag), and by the resultant reduction in binding of the marker to the solid phase.
