General description

Octaethylene glycol monododecyl ether is a nonionic detergent.

Application

Detergent used for the study of membrane proteins in a native-like state, e.g. ATPase. Used in a mixed micellar assay for lipoxygenase acting at neutral pH and for functional reconstitution of influenza virus envelopes.

Many membrane proteins become labile when they are solubilized by detergent. Here we show that the presence of high concentrations of glycyl betaine stabilizes one of these proteins, the sarcoplasmic reticulum Ca(2+)-ATPase (SERCA1a), solubilized with nonionic detergents like n-dodecyl beta-d-maltopyranoside

The effects of a nonionic surfactant, octaethyleneglycol mono n-dodecyl ether (C12E8), on the electroporation of planar bilayer lipid membranes made of the synthetic lipid 1-pamitoyl 2-oleoyl phosphatidylcholine (POPC), was studied. High-amplitude ( approximately 100-450 mV) rectangular voltage pulses were used

Many attempts have been made to rationalize the use of detergents for membrane protein studies [J. Biol. Chem. 264 (1989) 4907]. The barrier properties of the detergent headgroup may be one parameter critically involved in protein protection. In this paper
