WebFixing Samples for IHC. Fixation preserves tissue for future analysis by preventing autolysis (cell destruction mediated by a cell’s own enzymes) and decay. For the best results, tissue should undergo rapid and uniform fixation. This can be achieved by two methods: whole animal perfusion or tissue/organ immersion in fixative. WebAntigen retrieval can reveal epitopes masked during the preparation of tissues for staining. The protocol below describes a technique used by R&D Systems and can be used on both cryostat and paraffin-embedded sections. The protocol can be used with R&D Systems Acidic, Basic, or Universal Antigen Retrieval Reagents.
