Information about Eosinophilic

Main article: Eosin
Eosinophilic means "loves eosin", and refers to the staining of certain tissues, cells, or organelles after they been washed with eosin, a dye.

Eosin is an acidic dye, thus the structure being stained is basic.

Eosinophilic describes the appearance of cells and structures seen in histological sections which take up the staining dye, eosin. This is a bright pink dye that stains the cytoplasm of cells as well as extracellular proteins such as collagen.

Such eosinophilic structures are generally composed of protein.

The stain eosin is usually combined with a stain called haematoxylin to produce a haematoxylin and eosin stained section (also called an H&E, HE or H+E section). This is the most widely used histological stain in medical diagnosis - for example when a pathologist looks at a biopsy of a suspected cancer they will have the section stained with H&E.

Some structures seen inside cells are described as being eosinophilic, for example Lewy bodies, Mallory bodies.

    Histological section refers to thin slices of tissue applied to a microscopic slide, usually around 5 to 10 micrometres thick, which are viewed under a microscope.

    Sections are usually stained with dyes to give optical contrast before viewing.
