Mucicarmine stain
Mucicarmine Stain
Mucicarmine stain (pronunciation: myoo-si-kahr-min) is a type of histological stain used in pathology to stain mucin. Mucin is a type of protein produced by different types of cells in the body, including those in the gastrointestinal tract, respiratory tract, and reproductive system.
Etymology
The term "mucicarmine" is derived from the words "mucin", referring to the type of protein it stains, and "carmine", a bright red pigment derived from the Cochineal insect.
Usage
Mucicarmine stain is particularly useful in identifying and differentiating mucinous carcinoma from other types of carcinoma. It is also used to identify Cryptosporidium, a type of parasite that can cause gastroenteritis in humans.
Procedure
The procedure for using mucicarmine stain involves applying the stain to a tissue sample, then rinsing it off. The mucin in the sample will retain the stain, making it visible under a microscope.
