5 dni temu · Histological staining is based on a chemical basis wherein stains or dyes interact with various components of cells to selectively colour certain structures. The process of staining requires the attraction of oppositely charged ions by electrostatic forces.
For routine diagnosis, the use of H&E staining is by far preferred for viewing cellular & tissue structure detail. Learn about best practices, protocol & more.
2 paź 2024 · Hematoxylin and Eosin (H&E) most common stain used in histology. Hematoxylin. Stain that stains acidic structures blue/purple. Areas of the cell that contain lots of DNA and RNA, such as the nucleus and rough ER, will stain dark blue/purple. because they bind to hematoxylin. Eosin.
Explain what color you expect the RER and the SER to stain under H&E. If there is a difference, why? Answer: RER should be basophilic because of the presence of ribosomes, whereas SER should appear more eosinophilic.
To perform an H&E stain, follow the procedure below to re-hydrate, dehydrate and stain the tissue sections. Same solvents can be used for multiple tissue sections but should be changed daily or more often if they become contaminated (strongly colored by the stains). References: 1.

Routine H&E staining plays a critical role in tissue-based diagnosis or research. By coloring otherwise transparent tissue sections, this stain allows highly trained pathologists and researchers to view, under a microscope, tissue morphology.
H&E staining. The most commonly used staining system is called H&E (Haemotoxylin and Eosin). H&E contains the two dyes haemotoxylin and eosin. Eosin is an acidic dye: it is negatively charged (general formula for acidic dyes is: Na + dye-). It stains basic (or acidophilic) structures red or pink. This is also sometimes termed 'eosinophilic'.
