General description

Absorbance (10%, H₂O, 260 nm):≤0.3; conductivity (100 mM, H₂O):≤100 µmhos.

Highly purified non-ionic detergent intended for solubilizing membrane-bound proteins in their native state. Aggregation number: 84.

A highly purified nonionic detergent intended for solubilizing membrane-bound proteins in their native state, and for the preparation of lipid vesicles. Its well-defined chemical structure, small uniform micelles, and high water solubility make it superior to most other nonionic detergents for membrane solubilization. Because of its high critical micelle concentration (20-15 mM), it has the additional advantage of being removed easily by dialysis when compared to bile salts. Aggregation number: 84.
