Figure 4. 31P-phosphorus NMR spectra of C8E5 (blue) and DMPC (red). The chemical shift of DHPC is 35.1 ppm and the chemical shift of DMPC appears at 42.0 ppm for DMPC in DMPC / DHPC bicelles and 42.5 ppm in DMPC / C8E5 bicelles. Panel A is the sample analyzed at 25 ⁰C and Panel B is the sample analyzed at 37 ⁰C. Note: Data was also collected at 31 ⁰C showing chemical shifts similar to 37 ⁰C. (spectrum not shown).
