Immunohistochemistry

Immunohistochemistry (IHC) is a cornerstone technique in modern diagnostic pathology, enabling the visualization of specific antigens in tissue sections using antibody-based detection. This tertiary-level topic delves into the fundamental principles of antigen-antibody interactions, the production and use of monoclonal and polyclonal antibodies, and the various labeling systems including enzyme labels like horseradish peroxidase and alkaline phosphatase. It covers the complete IHC procedure from tissue fixation and antigen retrieval to blocking, primary antibody application, detection methods (direct, indirect, PAP, ABC, polymer-based), and counterstaining. For Zambian college and university students in biomedical science, histopathology, or medical laboratory science programs, mastering IHC is crucial for tumor classification, infectious agent identification, prognostic factor assessment, and research applications. This knowledge directly supports exam preparation, practical laboratory competency, and future careers in hospitals, research institutes, and diagnostic centers throughout Zambia's healthcare system.
