Eosin - Wikipedia
Eosin 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 eosin.
Eosin | Properties, Available variants & Uses - Macsen Labs
Eosin is a fluorescent, xanthene dye or red dye formed with the action of bromine and fluorescein which binds to salts with eosinophilic compounds containing positive charges. In order to understand the general histological architecture of tissues, eosin is the most suitable stain combined with an alum hematoxylin.

Hematoxylin and eosin staining of tissue and cell sections
2008年5月1日 · Hematoxylin has a deep blue-purple color and stains nucleic acids by a complex, incompletely understood reaction. Eosin is pink and stains proteins nonspecifically. In a typical tissue, nuclei are stained blue, whereas the cytoplasm and extracellular matrix have varying degrees of pink staining.

Eosin: a versatile organic dye whose synthetic uses keep expanding
Here, excited state eosin can abstract a hydrogen atom with a low bond dissociation enthalpy (BDE) from one substrate to furnish a radical (usually, stabilised by an adjacent heteroatom or conjugating functionality – hence the lower BDE). This radical then reacts with a second substrate to give the desired adduct.
H&E stain - Wikipedia
Main types of staining seen on H&E stain. Retina (part of the eye) stained with hematoxylin and eosin, cell nuclei stained blue-purple and extracellular material stained pink. Hematoxylin and eosin stain (or haematoxylin and eosin stain or hematoxylin-eosin stain; often abbreviated as H&E stain or HE stain) is one of the principal tissue stains ...
Eosin: a versatile organic dye whose synthetic uses keep expanding
Eosin: a versatile organic dye whose synthetic uses keep expanding. Organic dyes, which absorb light in the visible region of the electromagnetic spectrum, offer a lower cost, greener alternative to precious metals in photocatalysis. In this context, the organic dye eosin's uses are currently expanding at a significant rate.
Eosin Y - Wikipedia
It is commonly used in histology, most notably in the H&E (Haematoxylin and Eosin) stain. [1] Eosin Y is also widely used in the Papanicolaou stain (or Pap stain used in the Pap test) and the Romanowsky type cytologic stains. [1][2] It is also used as …
