N-Lauroylsarcosine sodium salt

N-Lauroylsarcosine is an anionic detergent.


N-Lauroylsarcosine is used for solubilization and separation of membrane proteins and glycoproteins; reported to inhibit hexokinase. It is useful in concentrated salt solutions used in the cell lysis step during RNA purification (helps avoid excessive foaming). It has been used to indicate paramagnetic anisotropy sign change in micelle mesophage. Inhibits bacterial flora of human saliva/gut at 0.25% as well as acting as a fungistatic agent in aqueous dispersion (1%).
