Chem Phys Lipids. 1990 Sep;55(3):351-4
Authors: Eisele JL, Neumann JM, Chachaty C
The colloidal features of short chain phospholipids can be deduced from 31P-NMR analysis by comparison with available data on phospholipid aqueous dispersion. In this study with dihexanoyl phosphatidylcholine, detergent phase separation was obtained by temperature shift and by addition of the precipitating agent polyethylene glycol. The 31P-NMR spectra indicate that the detergent micelles fuse to enter the hexagonal HII and lamellar phases. Consequences for the crystallization of membrane proteins are discussed.

One of the major obstacles to membrane protein (MP) structural studies is the destabilizing effect of detergents. Amphipols (APols) are short amphipathic polymers that can substitute for detergents to keep MPs water-soluble under mild conditions. In the present work, we have explored the...
