Eosin yellow, also known as eosin Y, is typically prepared by dissolving eosin powder in a solvent such as distilled water or ethanol. The concentration can vary depending on the intended use, but a common preparation involves adding about 1 gram of eosin to 100 mL of solvent. The solution should be stirred until fully dissolved, and it can be filtered to remove any undissolved particles. Once prepared, the eosin yellow solution can be stored in a dark container to prevent degradation from light.

Eosin is a red/pink acidic dye used in histology to stain cytoplasmic components such as proteins and muscle fibers. It is often used in combination with hematoxylin to provide contrast in tissue samples for microscopic examination. Eosin is commonly used in the H&E (hematoxylin and eosin) stain, one of the most widely used staining techniques in pathology.
