Eosin 1 %, aqueous in NaCl 0.9 %
Eosin 1%, aqueous in NaCl 0.9% is a solution containing the synthetic dye eosin (tetrabromofluorescein, molecular formula: C_20H_8Br_4O_5) at a 1% concentration, dissolved in a 0.9% sodium chloride (NaCl) solution. This eosin solution is widely used in histology and cytology to stain cell structures and the extracellular matrix. Eosin has a high affinity for basic structures such as proteins and typically stains them pink or red.
The use of a 0.9% NaCl solution as a carrier medium for the eosin has several advantages. First, it is isotonic, which means that it does not alter the osmotic pressure of the tissue, thus better preserving cellular structures. Second, the use of a NaCl solution promotes uniform staining and improves differentiation of cellular and extracellular structures because the salt aids diffusion of the dye into the tissue.
Eosin 1%, aqueous in NaCl 0.9% is therefore a good choice for histological and cytological applications where uniform staining and improved differentiation of cellular and extracellular structures are important. The use of NaCl as a carrier medium provides optimal staining that preserves the morphological characteristics of cells and tissues and allows sufficient differentiation of cellular and extracellular structures.
