Different types of model membrane samples suitable for studying membrane proteins by NMR spectroscopy: (A) lipid bilayers (inset) are present in multilamellar vesicles; (B) small unilamellar vesicles and macroscopically-aligned bilayer samples using either (C) glass plates or (D) cylindrical nanopores in anodic aluminum oxide. (E) Micelles are formed from pure detergents. When lipid and detergent mix, isotropic bicelles (F) and magnetically-aligned bicelles (G) are formed. Light gray color indicates a lipid bilayer, dark gray is detergent, and hatching represents either a glass plate (C) or aluminum oxide (D) as solid supporting material.
