Biological Role(s): food colouring
A food additive that imparts colour to food. In European countries, E-numbers for permitted food colours are from E 100 to E 199, divided into yellows (E 100-109), oranges (E 110-119), reds (E 120-129), blues and violets (E 130-139), greens (E 140-149), browns and blacks (E 150-159), and others (E 160-199).
Application(s): histological dye
A dye used in microscopic or electron microscopic examination of cells and tissues to give contrast and to highlight particular features of interest, such as nuclei and cytoplasm.
fluorochrome
A fluorescent dye used to stain biological specimens.
