Applications

• Has all the advantages of sulfobetaine containing detergents: hydrophobic, bile salt, and anionic detergents in a single molecule.
• Better at solubilizing proteins and breaking protein-protein interactions.
• Less protein aggregation than non-ionic detergents.
• Capable of solubilizing opiate receptors.
• CHAPS can be removed from protein solutions with a detergent removing gel or by dialysis.
