Biological activity:
CHAPS, a derivative of Cholic acid, is a zwitterionic detergent that solubilizes membrane proteins. CHAPS is used to stabilize various protein-DNA complexes and can retain the biochemical activity of proteins in solution.
Purpose:
CHAPS is a nondenaturing zwitterionic detergent used in membrane biochemistry. It can be used to dissolve membrane proteins as well as to interrupt protein-protein interactions. CHAPS has a low micelle molecular weight (6,150) and a high critical micelle concentration (6-10mM), and thus can be removed from the sample by dialysis. It is also suitable for solubilizing proteins in isoelectric focusing and two-dimensional electrophoresis. CHAPS is commonly used for nondenaturing (urea-free) isoelectric focusing and has been found to yield excellent resolution for certain subcellular preparations and plant proteins. "Concentrations between 2-4%(w/v) are typically used for isoelectric focusing gels."
