Concentration of chaps detergent for dialysis
WebSep 18, 1980 · Efficiency of detergent removal by dialysis depends on the detergent. However, even for sodium deoxycholate, a detergent possessing a large critical micelle concentration, there are approx. 7 molecules of deoxycholate per 1000 molecules of phospholipid retained by the bilayer even after extensive (310 h) dialysis. WebCHAPS is a non-denaturing, electrically neutral, sulfobetaine dtergent. It is used for solubilizing membrane proteins and breaking protein-protein interactions. It causes less protein aggregation than non ionic detergents and is capable of solubilizing poiate receptors. CHAPS can be removed from proteins by detergent removing gel or dialysis.
