Immunohistochemistry is the study of the intracellular distribution of antigens based on the formation of an immune complex. The concept is based on the application of a specific antibody to the antigen to be detected and visualization of the antigen-antibody reaction with a staining procedure. Immunohistochemical staining allows direct observation of antigenic expression at the cellular level.
