Alcian blue stain
Alcian Blue Stain
Alcian Blue Stain (pronunciation: al-see-an blue stain) is a widely used histological stain in the field of pathology. It is primarily used to identify and visualize acidic polysaccharides such as glycosaminoglycans in tissues.
Etymology
The term "Alcian Blue" is derived from the name of the company that first produced it, the ICI Company, previously known as the Alkali Cyan Company. The term "stain" comes from the Old English word "stænian," which means to color or dye.
Usage
Alcian Blue Stain is used in histology to stain acidic polysaccharides and mucins. It is particularly useful in identifying and visualizing these substances in tissue samples. The stain binds to the acidic components of these substances, allowing them to be seen under a microscope.
