ABSTRACT:
Method and apparatus for the detection of antibodies and antigens based upon the effect that any arbitrary antigen will adsorb onto a substrate in a monomolecular layer only, but that a corresponding specific antibody for such arbitrary antigen will bond thereto to form a bimolecular layer on the substrate. A first layer of antigen is adsorbed onto a substrate and the coated substrate is then exposed to a solution suspected of containing the specific antibody of interest. The substrate is then examined to determine whether a monomolecular or bimolecular layer is adhering thereon. Optical, including visual, electrical, and chemical means for examining the coated substrate are disclosed. The method can be reversed by replacing the antigen in each step above with its specifically reacting antibody and by replacing the antibody with its specific antigen.
