Fast Green FCF, Fast Green FCF also, Food green 3, FD & C Green No.. 3, Green 1724, Solid Green FCF, and C. I. 42053, is a bluish - green triphenylmethane dye that is used outside the EU as a food color E143.

Properties

Fast Green FCF (of English. For coloring food, food coloring ') is used in histology as a substitute for Light Green SF in the Masson- trichrome stain, because its color is stronger and less fade with time. Fast Green FCF is used at alkaline pH for staining of histones by a DNA purification. In agarose gel electrophoresis, Fast Green FCF is sometimes added to the sample buffer, where it is used for the solvent front marker. SDS- PAGE and Western blot, it is sometimes used for reversible protein staining. The absorption maximum is at 620-625 nm

Fast Green FCF is hardly absorbed in the intestine. Fast Green FCF is not approved, among others, in the EU as a food additive. In the U.S. it is canned peas and other green vegetables, jelly, sauces, fish, desserts, and baked goods up to 100 mg / kg added.

In animal studies, carcinogenic effects were noted, as well as mutagenic effects in cell cultures, experimental animals and humans. In higher concentrations, it can cause irritation to the eyes, skin, digestive tract and respiratory tract. Fast Green FCF in cell cultures has neurotoxic properties.
