NMR spectra (35°C) of magnetically aligned bicelles: DMPC/DHPC (q = 4.5) + 1 mol % DMPE-PEG 2000. (A) 2H NMR spectrum of HDO. The residual quadrupolar splitting of 30 Hz indicates magnetic alignment of bicelles. (B) 31P NMR spectrum showing resonances from DMPC (−12.4 ppm) and DHPC (−6.1 ppm), DMPC/DHPC intensity ratio of 4.5:1. The position of the DMPC resonance is indicative of bicelles aligned with their normal to the plane of the bilayer oriented perpendicular to the direction of the magnetic field. The resonance from 1 mol % DMPE-PEG 2000 is not resolved.
