More precisely, the effect of the CTAB is depending on the salt (e.g.
NaCl) concentration. This property is used in several protocol
to extract DNA from plants, fungi and bacteria. Depending on the salt
concentration, you will let resuspend either proteins or DNA.
Moreover, CTAB is commonly used as a disinfectant according to its
solubilizing (i.e. lyze of bacteria) properties. In France: cetavlon.
