Abstract
A method for the detection of antibodies immunochemically bound to the corresponding antigen fixed to a smooth surface of glass, metal, polymerfilm or the like. The surface with antigen bound antibodies is contacted with a suspension of small water-insoluble particles to which a biopolymer is directly bound, said biopolymer having the ability of binding to said antibodies, preferably at a non-antigen binding structure of the antibodies. The particles are then adsorbed only on that part of the surface where antibodies are specifically bound and the adsorbed particles forms a coating that is clearly visible by the eye.
