Figure 25 The phase diagram of a lipid-DNA mixture involving ''curvature-loving'' helper lipid. The spontaneous curvature of the helper lipid is c —1/25 A_1. For the cationic lipid, the spontaneous curvature taken is c = 0 A — 1. The bending rigidity for both lipids is Kc = 10 kBT. The symbols S, H, B, I, and D denote, respectively, the Lca, HCI, La, HII, and uncomplexed (naked) DNA phases. The broken line marks the single HcII phase.
