(A) Hydrodynamic diameter of CAM-lipid complexes in HEPES (10 mM, pH = 7.4) buffer with different weight ratios using DLS. (B) Zeta potentials of CAM-lipid complexes in HEPES (10 mM, pH = 7.4) with different weight ratios. Lipofectamine was used as control, data represent mean ± standard deviation (n=3). (C) Electrophoresis gel, lanes 1–9 correspond to 9N-lipid weight ratios of 1:0, 10:1, 5:1, 2:1, 1:1, 1:2, 1:5, 1:10, 0:1 at N/P ratio of 50, lane 10 is Lipofectamine, lane 11 is siRNA alone. (D) TEM image of CAM (9N)-lipid at 1:1 weight ratio.
