Description

General description

Acid fuchsine (C.I. 42685) is a sulfonated triaminotriphenylmethane. It is also known as acid magenta. At pH 12-14, acid fuchsine changes from red to colorless.

Application

Acid fuchsine is used as a biological stain in preparations including the histopathological polychrome of Pianese, the Ehrlich-Biondi triacid procedure for blood smears, and the Altmann stain for mitochondria. Various polychrome stains like the Masson polychrome variant; Van Gieson, and Mallory connective tissue stains contain Acid fuchsine.Other applications of acid fuchsine in biology and medicine involve fluorescent staining of latent fingerprints, the tracking of water flow within plants, and adding into an agar growth medium for yeasts.

Suitability

Certified for use in Van Gieson connective tissue stain.
