Effects of the addition of various lipids on the translational diffusion coefficients of DDM micelles in aqueous solution at pH = 7.5 and T = 298K, D_t,em, measured with micro-coil PFG-STE NMR experiments^[12–15]. Same presentation as in Figure 1. The following additives were studied: (A) PC. (B) CHS. (C) Comparison of the three lipids PC, PE and PI. (D) Comparison of PC, PE and PI when added to CHS-doped DDM micelles. In each panel the hydrodynamic radii for equivalent spheres, R_h, are indicated, as derived from the effective diffusion coefficients at infinite dilution, $D_{t,em}^0$. For those systems where the uptake of the lipid into the micelles could be monitored with measurements of the NMR signal intensities (see text and Figures 2, S1, S2 and S4), the approximate amounts of lipid solubilized in the DDM or DDM/CHS micelles are indicated as the lipid:DDM ratios.
