Descrizione generale

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.

Applicazioni

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.
A nondenaturing zwitterionic detergent with characteristics similar to CHAPS, although it is more soluble due to a more polar head group. Useful for the solubilization of integral membrane proteins.

Crystallization of membrane proteins remains a significant challenge. For proteins resistant to the traditional approach of directly crystallizing from detergents, lipidic phase crystallization can be a powerful tool. Bicelles are an excellent medium for crystallizing membrane proteins in a lipidic

Presenilins are polytopic, integral proteins that control intramembranous proteolysis at the "gamma-" and "epsilon-" cleavage sites of the Alzheimer amyloid-beta precursor protein (APP) to yield amyloid-beta peptide (Abeta) and the APP intracellular domain (AICD). We have overexpressed a constitutively active
