설명

애플리케이션

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.

생화학적/생리학적 작용

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.
