eosin (Meaning)
eosin (n)
a red fluorescent dye resulting from the action of bromine on fluorescein; used in cosmetics and as a biological stain for studying cell structures
eosin (n.)
A yellow or brownish red dyestuff obtained by the action of bromine on fluorescein, and named from the fine rose-red which it imparts to silk. It is also used for making a fine red ink. Its solution is fluorescent.

eosin Sentence Examples
- In histology, eosin is commonly used as a counterstain to hematoxylin, resulting in the classic purple and pink staining pattern seen in many tissues.
- The eosin Y dye is widely employed in histological staining techniques due to its contrasting properties, specifically its ability to impart a pink or reddish color to acidic cellular components.
- Eosin Y, a synthetic dye, is often used in histology for staining tissues, as it selectively binds to basic structures such as proteins, imparting a vibrant pink or orange-red color.
- The eosinophil, a type of white blood cell, is named after its affinity for eosin, specifically eosin Y, which stains its cytoplasmic granules a characteristic reddish-orange hue.
- Eosin Y is a versatile dye with applications beyond histology; it is also employed in textile dyeing, where it imparts a red or pink color to fabrics.
- Eosin is capable of detecting the presence of certain carbohydrates, such as glycogen and mucin, rendering them visible and distinguishable in histological preparations.
- In the context of Romanowsky stains, such as Wright-Giemsa and Leishman stains, eosin is one of the crucial components, contributing to the characteristic differentiation of blood cells, rendering them distinct and easily recognizable under a microscope.
- Eosin's acidic nature makes it particularly useful in staining basic structures, creating a counterbalance to the basophilic dyes commonly employed in histological staining protocols.
- Eosin can serve as a differentiating agent in certain staining techniques, selectively highlighting specific cell components or tissue structures based on their affinity for the dye.
- Eosin is not only limited to microscopy applications; it has also found utility in the field of cytology, particularly in the staining of cytological smears, enabling the examination and interpretation of cells at a microscopic level.
