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.
Application:	CHAPSO has been used: • in a study to assess the processes of liposome solubilization and reconstitution of two transport proteins • in a study to investigate a novel bicelle system for orienting macromolecules over a wide temperature range • as a mixture with dilauroyl phosphatidylcholine (DLPC) in solid-state nuclear magnetic resonance (NMR) technique to study membrane-associated proteins
General description:	CHAPSO is a non-denaturing zwitterionic bile salt derivative, derived from Chaps by the addition of a functional hydroxyl group.
