Immunohistochemistry

Immunohistochemistry describes the localization of antigens in histological and cytological preparations using antibodies. It is now recognized as an essential element and a major tool, both in diagnostic and research-orientated cellular pathology. The technique involves the detection of specific or highly selective cellular epitopes with an antibody and appropriate labelling system. Immunohistochemistry can be performed on cytological preparations, frozen sections and paraffin-embedded histological sections.
