- Extra Details:
- Eosin Y; also known as eosin; is a synthetic xanthene dye; appearing as a pink or rose-colored powder. Its molecular formula is C₂₀H₆O₅Br₄Na₂; with a molecular weight of 691.86. Eosin Y is commonly used in combination with hematoxylin for staining normal and pathological tissue structures. The aqueous form of Eosin Y contains a quinoid benzene ring chromophore and two acidic auxochrome groups (R–COONa and R–ONa) that form sodium salts. In aqueous solution; this acid dye dissociates into a negatively charged colored ion (R–COO⁻; R–O⁻) and a positively charged sodium ion (Na⁺). During staining; the negatively charged colored portion of Eosin Y binds via ionic interactions to positively charged components in the tissue; resulting in visible coloration. EnkiLife’s aqueous Eosin Y staining solution is prepared using high-quality imported raw materials and a proprietary preservative. The formulation is user-friendly and avoids the use of toxic reagents such as mercury or methanol. This product is suitable for staining tissue sections and cultured cells; and is typically used in conjunction with hematoxylin. It can also be applied following immunofluorescence or immunohistochemical staining—either as a counterstain after immunostaining; or prior to additional fluorescent labeling. The solution can be reused until staining efficacy declines. After staining; the cytoplasm appears pink to red.
