Application
Chromotrope FB has been used in indirect competitive CLIA (icCLIA) to detect its presence in foods.
Biochem/physiol Actions
Chromotrope FB, also known as acid red 14 (AR14), is a bright orange-red powder. It belongs to the class of monoazides. Chromotrope FB efficiently stains fatty substances and is also used to dye food and medicines.

Pregnant rats received 14C-Carmoisine (200 mg kg-1; 25 microCi) by gavage on days 16-19 of gestation. The animals were killed and maternal tissues, amniotic fluid, placentae, foetal membranes and foetuses were analyzed for radioactivity. No evidence for the transplacental transfer

Our histochemical and ultrastructural studies have identified, in human catecholamine locus coeruleus (LC) neurons, abundant and large spherical protein bodies (PB), containing histone-like, arginine-rich proteins, which originate as dense bodies in mitochondria. This species-specific phenotype in the neurons of man
