What is the Role of Amino Acids in Tissue Staining?
Histological staining techniques often rely on the chemical properties of amino acids. For example, Hematoxylin and Eosin (H&E) staining exploits the affinity of basic amino acids for hematoxylin, which binds to nucleic acids, and the affinity of acidic amino acids for eosin, which stains cytoplasmic components. Understanding the amino acid composition of proteins in tissues helps in choosing the appropriate staining method to highlight specific cellular structures.
