Description
Eosin yellow solution (W/V) refers to a liquid solution containing eosin yellow, a synthetic dye commonly used in histology and cytology staining procedures. The concentration of eosin yellow in the solution is expressed as a weight per volume percentage (% w/v). Eosin yellow is a water-soluble dye that selectively stains acidic cellular components such as cytoplasm, red blood cells, and collagen fibers. It imparts a pink to red color to the stained tissues, enhancing the contrast and visibility of cellular structures under a microscope. Eosin yellow solution is widely employed in tissue processing and staining protocols for the preparation of histological specimens.
