Sample protocol NMR samples consisted of 22 mg of 31d-PAPC. Lipids were mixed as CHCl3 solutions and then dried under N2 and vacuum. MLV suspensions (28−60 mM) were prepared by vigorous vortexing of lipids in 0.6 mL of bufer solution.

DETAILS The typical spectrum resulted from 24−48k scans of the two-pulse sequence with a 90° pulse of 3.75−3.95 μs, an interpulse spacing of 40 μs, and a dwell time of 2 μs. The delay between acquisitions was 300 ms, and 4K data points per acquisition were collected in quadrature with 8-cyclops phase cycling. Spectra were de-Paked.
