Descrizione

Descrizione generale

Conductivity (1.0 M, 24°C): <100 µmhos.

Non-denaturing zwitterionic detergent that combines features of bile salts and N-alkyl sulfobetaines. Better at solubilizing proteins than the structurally related carboxylic acid anions, and is more effective at breaking protein-protein interactions than either sodium cholate or TRITON^™ X-100. Capable of solubilizing the opiate receptor to a state exhibiting reversible binding to opiates. Also capable of disaggregating P 450 to its monomeric form without denaturation. Has a small micellar molecular weight (6150 Daltons) and a high critical micellar concentration (6-10 mM). Can be removed from either gels or protein solutions by dialysis. Aggregation number: 4-14.

Capable of solubilizing the opiate receptor to a state exhibiting reversible binding of opiates. Also, capable of disaggregating cytochrome P450 to its monomeric form without denaturation. Has a small micellar molecular weight and a high critical micellar concentration and can be removed from either gels or protein solutions by dialysis across a membrane. Aggregation number: 4-14.

Applicazioni

CHAPS is a nondenaturing zwitterionic detergent for membrane biochemistry.
Useful for solubilizing membrane proteins and breaking protein-protein interactions. CHAPS′ small micellar molecular weight (6,150) and high critical micelle concentration (6-10 mM) allow it to be removed from samples by dialysis. It is also suitable for protein solubilization for isoelectric focusing and two-dimensional electrophoresis. CHAPS is commonly used for non-denaturing (without urea) IEF and has been shown to give excellent resolution of some subcellular preparations and plant proteins. Concentrations between 2-4% (w/v) are typically used in an IEF gel.

Attenzione

Toxicity: Harmful (C)

Ricostituzione

Following reconstitution, store in the refrigerator (4°C). Stock solutions are stable for up to 6 months at 4°C.
