CHAPS 是一种两性离子洗涤剂，是一种 Cholic acid 的衍生物，可溶解膜蛋白。它用于稳定各种蛋白质-DNA 复合物，并可以保留溶液中蛋白质的生化活性。

CHAPS is a zwitterionic nondenaturing detergent for solubilizing membrane proteins.

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.
