The thermal properties of dilauryl phosphatidylethanolamine liposomes are affected by lipid source and preparation.
Dilauryl phosphatidylethanolamine (DLPE) dispersions in water ('liposomes') display phase metastability. We find, by differential scanning calorimetry (d.s.c.), that the new phases are dependent upon lipid source and temperature of initial hydration. These observations may explain inconsistencies in the reported metastability behaviour of saturated PEs.
