CHAPS on the other hand forms smaller aggregates (6,000 MW) when concentration rises above 10 mM. In addition, Triton X100 forms large (greater than 90,000 MW) aggregates when concentration rises above 0.25 mM. It has hydrophobic regions but also a head group with a negative charge (in normal saline). It has both hydrophilic and hydrophobic regions, but no net charges.

Both detergents have low light absorbance in the ultraviolet region of the electromagnetic spectrum, which is useful for laboratory workers monitoring ongoing chemical reactions or protein-protein binding with UV/Vis spectroscopy. What is the difference between CHAPS and CHAPSO detergents?Ī related detergent, called CHAPSO, has the same basic chemical structure with an additional hydroxyl functional group. Yes, this detergent’s small micellar molecular weight and high critical micelle concentration (6-10 mM) allow it to be removed from samples by dialysis. Can CHAPS detergent be removed from samples by dialysis? What is the stability of this detergent?ĬHAPS biodetergent is moisture sensitive and hygroscopic. Solutions of up to 1 M (60%) can be made in this way. How can I make a CHAPS 10% solution?įor a 10% solution (i.e., 1 g CHAPS solid into beaker followed by 9 g of water), cover beaker with watch glass and allow it to sit at room temperature for 30-60 minutes. It is preferable to avoid shaking and stirring mixtures when preparing CHAPS solutions. Yes, this detergent becomes a clear and colorless to slightly-yellow solution in water. What is the TLC of CHAPS (silica gel: methanol/NH4OH = 95/5)? CASģ-2-hydroxy-1-propanesulfonate 3-1-propanesulphonateīulk and custom orders available. It can be used as a non-toxic stabilizing agent for growth factors. Its small micellar molecular weight (6150) and high CMC (6-10 mM) allow it to be removed from samples by dialysis. A commonly used isoelectric focusing sample solution consists of 8 M urea, 4% CHAPS, 50-100 mM dithiothreitol (DTT) and 40 mM Tris. Concentrations between 1-4% (v/v) are typically used in an isoelectric focusing gel. This detergent has demonstrated excellent resolution of some sub-cellular preparations and plant proteins. CHAPS is commonly used for protein solubilization in isoelectric focusing and two-dimensional electrophoresis, especially for non-denaturing (without urea) isoelectric focusing. This detergent combines the useful properties of both sulfobetaine-type and the bile salt detergents. About CHAPS DetergentĬHAPS (formal name: 3-cholamidopropyl dimethylammonio 1-propanesulfonate) is a non-denaturing zwitterionic detergent for solubilizing membrane proteins and breaking protein-protein interactions. Commonly used for protein solubilization in isoelectric focusing and two-dimensional electrophoresis especially for non-denaturing (without urea) isoelectric focusing. Combines the useful properties of both the sulfobetaine-type and the bile salt detergents.
