Eosin: An Overview
Alternative Name
Tetrabromofluorescein
Eosin is a fluorescent dye belonging to the family of xanthene dyes. It is widely used in biological staining and medical diagnostics. The compound is known for its distinctive pinkish-red color, which is utilized in staining cytoplasm, collagen, and muscle fibers in histology and microbiology. Eosin works by binding to various cellular components, such as proteins, thereby highlighting them under a microscope.
Applications
- Biological staining
- Medical diagnostics
- Research
Chemical Structure
Eosin is chemically known as Tetrabromofluorescein, indicating the presence of four bromine atoms in its structure. This modification enhances its staining properties and solubility in biological specimens.
Usage in Histology
In histology, Eosin is commonly used in combination with Hematoxylin, where Hematoxylin stains cell nuclei blue, and Eosin stains the extracellular matrix and cytoplasmic components pink. This combination is known as H&E staining and is fundamental in medical diagnostics and research.
