Application
Erythrosin B has been used as a dye in fluorescence lifetime imaging.[1]
Biochem/physiol Actions
Erythrosin B, also called as eosin B, is a xanthene dye.[2] It belongs to the family of fluorescein dyes. Erythrosin B is an artificial food dye that induces hyperkinesis when swallowed by susceptible children. It plays a major role in inhibiting dopamine uptake and high affinity 3H-ouabain binding and ion transport in synaptosomes from rat caudate nucleus.[3][4]
Suitability
Counterstain to alum-hematoxylin.
