Eosinstained
Eosinstained is an adjective used in histology to describe a specimen that has been treated with eosin, an acidic dye used to color basic components of cells and tissues. In routine practice, eosin is part of the hematoxylin and eosin (H&E) staining protocol, which provides contrast by staining cytoplasm, muscle fibers, collagen, and other structures in pink to red, while nuclei are stained blue by hematoxylin.
Mechanism and appearance: Eosin binds to positively charged sites on proteins, particularly in cytoplasmic components and
Applications and interpretation: Eosin-stained sections are foundational in diagnostic histology and pathology. They support assessment of
