Sudan black B is a lysochrome (fat soluble dye) predominantly used for demonstrating triglycerides in frozen sections. It is also valuable for demonstrating some protein bound lipids in paraffin sections. It may also stain other materials, not being completely restricted to lipids as the other dyes used.

Compare this dye to the other common lysochromes sudan III, sudan IV and oil red O.
