Figure 2.
Synchrotron SAXS data, as a function of temperature, of a DOTAP/GMO (85:15, mol:mol) lipid mixture (without sDNA) at total lipid/water 60/40 (w/w). A) The SAXS scans reveal that the lipid mixture adopts the body-centered gyroid cubic structure (QIIG) with space group Ia3d up to T=80 °C. At this temperature the HII phase emerges (in coexistence with the QIIG phase) and the peaks characteristic for the HII phase are indicated by the black arrows. B) Lattice spacings of the HII (aH, red dots) and the QIIG (aQ, black dots) phases as a function of temperature.
