WebHow does immunohistochemistry staining work? Immunohistochemistry (IHC) uses antibodies to detect the location of proteins and other antigens in tissue sections. The antibody-antigen interaction is visualized using either chromogenic detection with a colored enzyme substrate, or fluorescent detection with a fluorescent dye. WebChromogenic IHC utilizes enzyme-catalyzed deposition of chromogens at the site of the antigen, while fluorescent IHC employs fluorophores and direct or indirect immunofluorescence to help visualize antigens of …
