EOSIN Y STAIN SOLUTION:

EOSIN Y stain solution 1%, Aqueous provides the key component of an Eosin Y Working Solution in the routine hematoxylin and eosin stain and can be used in either manual or automated staining platforms.  Eosin’s particular value is in its ability to distinguish between the cytoplasm of different types of cells by staining cytoplasmic components differing shades and intensities of pink to red.

The routine hematoxylin and eosin (H&E) stain is used for screening specimens in anatomic pathology, as well as for research, smears, touch preps and other applications.  Its two primary coloring agents stain all cellular material including nuclei (blue), and cytoplasmic elements (pink-red).  Popularity of this stain is due, in large measure, to its simplicity, ability to clearly demonstrate a wide variety of different tissue components, dependability, repeatability, and speed of use.

EOSIN Stain Solution Quality Control:

EOSIN Y Stain solution 1% is the foundation of the diagnostic process, maintaining quality is of critical importance. Change staining solutions on a regular basis according to laboratory protocol.  Procedures will vary between laboratories depending upon volume of slides, automation vs manual staining, chemical hygiene and solution integrity.  The longevity of eosin depends upon these factors and stain quality should be regularly screened with the use of an H&E control slide.
