Comparison of partial phase diagrams of GMO/DOTAP/DOPE-PEG and GMO/DOTAP/GMO-PEG in excess water. Primitive cubic phases $\left({\text{Q}}_{\parallel }^{\text{P}}\right)$ occupy a larger composition range in DOPE-PEG ternary mixtures than in GMO-PEG ternary mixtures, where the gyroid $\left({\text{Q}}_{\Vert }^{\text{G}}\right)$ is the dominant structure. GMO/DOTAP and GMO/DOTAP/GMO-PEG data were extracted from Leal et al.⁵ and Kim et al.,⁶ respectively.
