Description

CHAPSO (3‑[(3‑Cholamidopropyl)dimethylammonio]‑2‑hydroxy-1-propanesulfonate) is a high‑purity biochemical‑grade detergent supplied as a white powder, designed for membrane protein research and other sensitive biochemical applications. As a zwitterionic detergent, CHAPSO combines the ability to solubilize membrane-associated proteins with minimal disruption to their native structure and activity. Its high solubility, low UV absorbance, and mild detergent behavior make it an excellent choice for protein extraction, purification, reconstitution, and structural or functional studies.
