CHAPSO (3-[(3-Cholamidopropyl)dimethylammonio] 2-hydroxy-1-propanesulfonate) is a zwitterionic detergent used for solubilizing membrane proteins and is available in a 25g format. This detergent is highly effective in membrane protein research, as it offers mild solubilization while maintaining protein structure and functionality. CHAPSO is essential in membrane protein purification, protein-lipid interaction studies, and enzyme assays, as it solubilizes membrane components without denaturation. This formulation is widely used in applications that require efficient extraction and stabilization of membrane proteins for further analysis, including structural and functional studies in cell biology and biochemistry.
