Beschreibung

General description

Chapso is a zwitterionic detergent derived from Chaps by the addition of a functional hydroxyl group. It is a nondenaturing zwitterionic detergent with characteristics similar to CHAPS, although it is more soluble due to a more polar head group.

Application

Chapso has been used in a study to assess methods for high-throughput crystallization of membrane proteins. It has also been used in a study to investigate the effects of detergents on the structure of rhomboid proteases in a lipid environment.

Ein nicht denaturierendes, zwitterionisches Detergens mit ähnlichen Eigenschaften wie CHAPS, das jedoch aufgrund einer stärker polaren Kopfgruppe besser löslich ist. Für die Solubilisierung von integralen Membranproteinen geeignet.
