| Application: | Eosin Y disodium salt has been used for determining sperm viability. The swollen and stained spermatozoa were considered dead. In corneal epithelium, it has been used in the procedure of immunohistological staining. |
| Biochem/physiol Actions: | Eosin Y is a xanthene dye and is used for the differential staining of connective tissue and cytoplasm. In histopathology, it is applied as a counterstain after hematoxylin and before methylene blue. It is also used as a background stain, thereby giving contrast to the nuclear stains. |
