Is H and E stain used in cytology?
Conventional histological and cytological stains, including hematoxylin & eosin and Papanicolaou, are combined with immunohistochemistry and simultaneously evaluated on the same specimen slide by use of invisible chromogens..
What is cytology staining?

What is the stain of cytology?
The universal stain for cytological samples is the PAP stain developed by the Greek cytopathologist, George Papanico- laou.
He developed the polychrome staining reaction to study cell components, variations in cellular maturity, and metabolic activity..
What is the staining technique?
Staining, in microbiology, can be defined as a technique which is used to enhance and contrast a biological specimen at the microscopic level.
Stains and dyes are used to highlight the specimen at the microscopic level to study it at higher magnification for histopathological studies and diagnostic purposes..
- If the entire discipline of diagnostic cytopathology could be distilled into a single theme, it would be the Papanicolaou stain.
Yet it was the Romanowsky stain upon which the discipline of cytopathology was founded.
