It is not feasible to dissolve catalog number E4009 to a concentration of 1 to 5% in alcohol. For H&E staining or staining sperm for viability, Eosin Y disodium salt is typically used, rather than Eosin Y free acid. Dry dyes, available under catalog numbers E4382 or 861006, are also used, along with various solutions for H&E staining, which also utilize only Eosin Y disodium salt. A 5% Eosin Y solution is available with the catalog number 318906, which is also formulated with Eosin Y disodium salt.

Application
Eosin Y has been used as a stain:
- to determine the location of the brain sections
- for staining of fixed liver tissue
- for histological examination of brain sections from the dorsal hippocampus
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.

Is there a sample protocol for this product ? There id low solubility of E4009 in even ethanol (1 mg/mL) in that case how to make the usual eosin concentration of 1-5% w/v for use in an H&E staining reaction.
