Figure 6.

(A) Small-angle X-ray scattering data for DOTAP/DOPC/ergosterol–DNA complexes shows that their structure remains lamellar with increasing Φergosterol (first and second order of the lamellar peak are marked by q001 and q002). At Φergosterol ≥ 0.4, ergosterol crystals coexist with CL–DNA complexes (qergo, marked by grey arrows). Black arrowheads point to the DNA peak at qDNA. (B) X-ray diffraction data for DOTAP/DOPC/ergocalciferol–DNA complexes shows that at Φergocalciferol = 0.1, their structure is lamellar (first and second order of the lamellar peak are marked by q001 and q002). For Φergocalciferol ≥ 0.2, a second lamellar phase is observed (first and second order of its lamellar peak are marked by black arrows). At Φergocalciferol ≥ 0.4, ergocalciferol crystals coexist with CL–DNA complexes (qec, marked by grey arrows). Black arrowheads point to the DNA peak at qDNA.
