General description

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.

Application

CHAPSは非変性性の双性イオン界面活性剤で、膜の生化学研究に用いられます。
膜タンパク質の可溶化やタンパク質-タンパク質相互作用の阻害に有用です。CHAPSはミセルの分子量が小さく(6,150)、限界ミセル濃度が高い(6~10 mM)ため、透析によってサンプルから除去することが可能です。等電点電気泳動(IEF)および二次元電気泳動の際のタンパク質可溶化にも適しています。CHAPSは非変性の(尿素を使用しない)IEFで一般に用いられており、細胞内画分や植物タンパク質の分離で優れた性能を示しています。IEFゲルにおける通常の使用濃度は2~4% (w/v)です。

Preparation Note

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