Features
CHAPS is a non-denaturing, zwitterionic detergent derived from cholic acid. CHAPS is often used as a detergent in the solubilization and purification of membrane proteins for several advantageous reasons. CHAPS detergent is non-denaturing to membrane proteins, can solubilize proteins, disaggregate protein-protein interactions and is electrically neutral. CHAPS is also useful in ion exchange chromatography and isoelectric focusing as it is zwitterionic and does not exhibit a net charge between pH 2 to 12. The critical micelle concentration of CHAPS is 6-10mM.
A non-denaturing, zwitterionic detergent for membrane proteins
Applications
Buffer; zwitterionic nondenaturing detergent for solubilizing membrane proteins CHAPS is used in the laboratory to dissolve biological macromolecules such as proteins. It acts as a non-denaturing solvent used in purification of membrane proteins. It is also useful in conjunction with nonionic detergents like Triton X-100. Further, it is used as a non-denaturing zwitterionic detergent for membrane biochemistry.
