Descripción

General description

CHAPSO is a non-denaturing zwitterionic bile salt derivative,[1] derived from Chaps by the addition of a functional hydroxyl group.

Application

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.

CHAPSO has been used:

• in a study to assess the processes of liposome solubilization and reconstitution of two transport proteins[2]
• in a study to investigate a novel bicelle system for orienting macromolecules over a wide temperature range[3]
• as a mixture with dilauroyl phosphatidylcholine (DLPC) in solid-state nuclear magnetic resonance (NMR) technique to study membrane-associated proteins[4]
