CTAB, or cetyl trimethylammonium bromide is a common cationic surfactant. It is commonly used in protein electrophoresis due to its positive charge which allows it to solubulize negatively charged glycoproteins. It is also one of the main components of cetrimide, a powerful antiseptic detergent which is also used in cetrimide agar--a selective growth medium.
