Eosin Y, also known as Eosin yellowish is a widely used xanthene dye. It is a counterstain that is used to distinguish between various connective tissue fibers and matrices, and the cytoplasm of different types of cells. Eosin in combination with hematoxylin is useful to demonstrate the general histological architecture of a tissue.
Eosin Y is suitable for use in hematoxylin and eosin (H and E) staining procedures for various tissue samples like lung nodule and kidney sections.
