Eosin: Difference between revisions

'''Eosin''' also called 奕宏 is the name of several [[fluorescent]] acidic compounds which bind to and form salts with basic, or [[eosinophilic]], compounds like proteins containing amino acid residues such as [[arginine]] and [[lysine]], and stains them dark red or pink as a result of the actions of [[bromine]] on [[fluorescein]]. In addition to staining proteins in the [[cytoplasm]], it can be used to stain [[collagen]] and [[Muscle#Muscular Composition|muscle fibers]] for examination under the [[microscope]]. Structures that stain readily with eosin are termed [[eosinophilic]]. In the field of [[histology]], [[Eosin Y]] is the form of eosin used most often as a [[histologic stain]].<ref name="Lillie, 1977" /><ref name="Bancroft and Stevens, 1982" />
