WebDetergents with higher CMC values have weaker binding and are subsequently easier to remove by dialysis or displacement methods. Detergents with low CMC values require less detergent in order to form micelles and solubilize proteins or lipids. WebCHAPS is sulfobetaine derivative of cholic acid. This zwitterionic detergent is useful for membrane protein solubilization when it is important to maintain protein activity. CHAPS detergent is soluble over a wide range of pH (2 to 12) and is easily removed from solution by dialysis because it has a high critical micelle concentration (CMC).
