Overview

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.

CTAB is used in many applications including current research in rare metal nanostructure synthesis. [1], [2], [3]
