Carbol fuchsin
Carbol Fuchsin
Carbol fuchsin (pronounced: /ˈkɑːrbɒl ˈfuːksɪn/) is a mix of Phenol and Basic fuchsin, used in staining procedures in microbiology.
Etymology
The term "Carbol fuchsin" is derived from its two main components. "Carbol" is a shortened form of carbolic acid, an older name for phenol. "Fuchsin" is derived from the color fuchsia, named after the flower, due to the dye's bright pink color.
Usage
Carbol fuchsin is primarily used in the Ziehl-Neelsen stain, to identify Acid-fast bacteria, such as Mycobacterium tuberculosis. It is also used in the Schaeffer-Fulton stain to stain endospores.
