In the context of IHC, 'antigenicity' refers to the ability of a specific epitope on an antigen within a tissue section to be recognized and bound by its corresponding antibody. It is a measure of how well the antigen's structure has been preserved through tissue processing (fixation, embedding) and how accessible the epitope is. Good antigenicity means the epitope is intact and exposed, allowing for strong, specific antibody binding and clear staining. Poor antigenicity can result from several factors: 1) Denaturation or masking of the epitope by formalin cross-linking during fixation. 2) Degradation of the antigen due to delayed fixation or autolysis. 3) Damage from excessive heat during processing or retrieval. The goal of proper tissue handling and antigen retrieval is to preserve or restore antigenicity to ensure reliable IHC results.
