Embalagem

25, 100 g in glass bottle

Ações bioquímicas/fisiológicas

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.

Adequação

Certified for use as a counterstain against hematoxylin; as a constituent of Wright stain; in modified Nocht′s stain; as a constituent in eosin-methylene blue medium.
