Abstract
A method for immunochemical assay of an antigen or antibody by labelling the antigen or antibody with a specific cyanine or merocyanine dye containing a carboxy group followed by effecting an immune reaction and photochemical processing thereof is provided. The amount of the antigen or antibody is measured in term of optical density of developed silver halide which is brought into contact with either the antigen-antibody reaction product or the unreacted material. This immunochemical assay method gives high detection sensitivity in a simple operation manner.
