What are Common Biochemical Reactions in Histology?
Several biochemical reactions are commonly studied in histology:
Enzyme Reactions: Enzymes such as peroxidase and phosphatase are used as markers in histochemical staining. For example, the Gomori Trichrome Stain is used to identify muscle fibers, collagen, and fibrin. Lipid Reactions: Techniques like Oil Red O staining are used to identify lipids within tissues. Protein Reactions: Immunohistochemistry employs antibodies to detect specific proteins, such as receptors or enzymes, within tissues. Nucleic Acid Reactions: In situ hybridization techniques detect specific DNA or RNA sequences within tissue sections, providing insights into gene expression and localization.
