Eosin Y is a tetrabromo derivate of fluorescein.
Eosin B is a dibromo dinitro derivate of fluorescein.
For staining, eosin Y is typically used in concentrations of 1 to 5 percent weight by volume, dissolved in water or ethanol. For prevention of mold growth in aqueous solutions, thymol is sometimes added (The science of laboratory diagnosis By John Crocker, David Burnett (relevant citation for thymol inhibits growth of fungi). A small concentration (0.5 percent) of acetic acid usually gives a deeper red stain to the tissue.
