Medical Applications for Eosin
Some medical applications for eosin have shown substantial growth. Eosin Y, Acid Red 87; BSC Certified is vital in medicine and biological science to show details in cells and microorganisms. It highlights cell granules and nuclei, and mast cells (cells that create other cells). Eosin demonstrates the presence of viruses borne by mosquitoes, or early necrobiotic changes. It is used to characterize tissue cells, protozoans and bacteria. Eosin’s most important medical uses are in blood and bone-marrow testing, including the PAP smear.

What is Eosin?
Eosin is a water soluble dye, a “red crystalline powder, designated by the formula C20H8O5Br4, used in textile dyeing and ink manufacturing” or “the red sodium salt of this powder, used in biology to stain cells”, or “any of a class of red acid dyes of the xanthene group used as cytoplasmic stains and as counter-stains.” (Sources: The Free Dictionary – Eosin and The Medical Free Dictionary – Eosin). Further,
Eosin is an orange-pink dye … used to stain cytoplasm, collagen and muscle fibers for examination under the microscope.
Eosin is most often used as a counter-stain to haematoxylin in H&E (haematoxylin and eosin) staining. H&E staining is one of the most commonly used techniques in histology. Tissue stained with hematoxylin and eosin shows cytoplasm stained pink-orange and nuclei stained darkly, either blue or purple. Eosin also stains red blood cells intensely red. Eosin is an acidic dye and shows up in the basic parts of the cell, ie the cytoplasm. Hematoxylin however is a basic dye and shows up in the acidic part of the cell. For example the nucleus, where nucleic acids (DNA and RNA) are concentrated.
