Fuchsine (rosaniline hydrochloride) is a magenta dye. Basic fuchsine is a mixture of rosaniline, pararosaniline, new fuchsine and Magenta II. Carbol fuchsin is a mixture of phenol and basic fuchsin, used in bacterial staining procedures. It is commonly used in the staining of mycobacteria as it has an affinity for the mycolic acids found in their cell membranes. The World Health Organization recommendation of 0.3% carbol fuchsin in the ZN method for staining acid-fast bacilli (AFB).
