621.1.HTC_H&E Stain (Paraffin or Cryosections) v2

Hematoxylin and Eosin staining is the standard chemical stain used on slides to be reviewed for assessment of general histopathology and the generation of a pathology report for each donor. (From Wikipedia) H&E is the combination of two histological stains: hematoxylin and eosin. The hematoxylin stains cell nuclei a purplish blue, and eosin stains the extracellular matrix and cytoplasm pink, with other structures taking on different shades, hues, and combinations of these colors. Hence a pathologist can easily differentiate between the nuclear and cytoplasmic parts of a cell, and additionally, the overall patterns of coloration from the stain show the general layout and distribution of cells and provides a general overview of a tissue sample's structure. Pattern recognition, by expert humans or by software that aids those experts in digital pathology, provides histologic information. This stain combination was first introduced in 1876 by A. Wissowzky.
