Catalysts are essential in histology for several reasons:
Tissue Fixation: Enzymes help in cross-linking proteins and nucleic acids, preserving the tissue's structure. Staining: Enzyme-based stains can highlight specific cellular components, aiding in the visualization under a microscope. Antigen Retrieval: Enzymatic processes can unmask antigens, making them accessible for antibody binding in immunohistochemistry. Digestion: Enzymes break down specific tissue components, facilitating easier sectioning and analysis.
