The lamellar/nonlamellar phase preferences of lipid model membranes composed of mixtures of several cationic lipids with various zwitterionic and anionic phospholipids were examined by a combination of differential scanning calorimetry and (31)P NMR spectroscopy. All of the cationic lipids utilized in this study form only lamellar phases in isolation. Mixtures of these cationic lipids with zwitterionic strongly lamellar phase-preferring lipids such as phosphatidylcholine form only the lamellar… CONTINUE READING
