Sudan Black B Staining


Sudan Black B Staining is a special staining technique that uses a fat-soluble dye called Sudan Black B to stain lipids and lipid-containing structures in biological samples. Lipids are organic molecules that are insoluble in water but soluble in organic solvents. They include fats, oils, waxes, phospholipids, steroids, and some vitamins. Lipids play important roles in energy storage, cell membrane structure, hormone synthesis, and signal transduction.
