text: "Neutral vesicle-forming lipids" refers to any amphiphathic lipid or lipid mixture (i) capable of forming stable lipid bilayer vesicles in the presence of charged vesicle-forming lipids, at a selected concentration of charged lipids between 5-50 weight percent of total lipids, and (ii) having a polar head group with no net charge at a selected pH between 3.5-10.5, and preferably between about 5.5 and 8.5.
