WebWhen detergent meets bilayer: Birth and coming of age of lipid bicelles Published in final edited form as: 67, 68 ]. SLUV and bicellar phases can be inter-converted, and the interconversion can be used to generate small unilamellar vesicles of path-dependent size distribution and characteristic shape [ 68 ]. WebOur data suggest that detergent solubilization proceeds by a combination of 1) a transbilayer attack, following flip-flop of detergent molecules across the lipid bilayer, and 2) extraction of membrane components directly by detergent micelles.
WebThe lipid bilayer is a thin polar membrane made of two layers of lipid molecules. These membranes are flat sheets that form a continuous barrier around cells. The cell membrane of almost all living organisms and many viruses are made of a lipid bilayer, as are the membranes surrounding the cell nucleus and other sub-cellular structures. The ...
