(A) Spectra of SOPC, SOPC/cholesterol 85:15 mol %, and SOPC/cholesterol 70:30 mol % at 37°C. The first order spinning sidebands are shown in the inset with 20-fold magnification. (B) Temperature-dependent changes of 10 kHz 1H MAS NMR spectra of SOPC multilamellar vesicles. Superimposed spectra are shown to emphasize the presence of isosbestic points in the course of the gel-to-liquid crystalline phase transition. Bold lines show spectra taken at the highest (37°C) and at the lowest (2°C) temperatures. The first order spinning sidebands are shown in the inset with 20-fold magnification. (C) Temperature-dependent changes of 10 kHz 1H MAS NMR spectra of SOPC/cholesterol 70:30 multilamellar vesicles. Superimposed spectra are shown to emphasize the presence of isosbestic points in the phase coexistence region. Bold lines show spectra taken at the highest (37°C) and at the lowest (2°C) temperatures. The first order spinning sidebands are shown in the inset with 20-fold magnification.
