C.I.Direct Blue 199, also known as Acid Blue 9, or Direct Blue 199, is a type of synthetic sulfonic acid dye that exhibits excellent colorfastness and resistance to fading in water. This dye has found application as a protein stain in electrophoresis gels. The attraction between the fibers and the dye molecules occurs via van der Waals forces and hydrogen bonding. The dye molecules then permeate the fibers and are confined within the spaces between them, where they are stabilized by ionic bonding with the sulfonic acid groups present on the dye molecules and the surface of the fibers..
