Preparation of Small Unilamellar Vesicles by Sonication
[0095] Egg PC dissolved in chloroform was placed in a 100 ml vessel and dried to a thin film under an inert atmosphere of nitrogen. Sterile saline was added to the lipid film to a final concentration of about 100 mg / ml, and the lipid film was hydrated with swirling. The resulting multilamellar vesicle (MLV) suspension was then bath sonicated for 1 hour using a Heat System Sonicator, Model 375W, at a power setting of 40-50% full value. The temperature of the suspension was maintained at about 4° C. during sonication. Large vesicles or MLVs were separated from the sonicated suspension by ultracentrifugation at 100,000 g for 1 hour (Barenholz, Y. et al., Biochemistry (1977) 16:2806). The remaining suspension of SUVs, having a concentration of about 100 mg / ml, was then filter sterilized.

Preparation of Small Unilamellar Vesicles by Extrusion
[0096] Homogeneous small unilamellar vesicles (SUVs) of egg PC for human use with an average diameter of 65 nm±10 nm in size, in 0.15M NaCl, were prepared by extrusion using serial filtration through polycarbonate filters in a GH 76-400 pressure cell (Nucleopore) (Anselem, S., et al. In Gregoriadis, G. (ed). LIPOSOME TECHNOLOGY, pp. 501-524, CRC Press, Boca Raton, Fla. (1993)). These vesicles were empty SUVs.
[0097] Liposomal particle size was measured by Nicomp submicron laser particle sizer, by Quasielectric light scattering or comparable method. It can also be determined using a Coulter model N4 sub-micron particle analyzer equipped with a size distribution processor analyzer (Barenholz et al. In Gregoriadis, G. (ed), LIPOSOME TECHNOLOGY, pp. 524-607, CRC Press, Boca Raton, Fla. (1993)). The final extrusion step was through a 0.05 micrometer pore polycarbonate filter. Egg PC SUV's should be sterile and pyrogen-free and were s...

Alternative Preparation of Small Unilamellar Vesicles by Extrusion
[0112] Homogeneous small unilamellar vesicles (SUVs) of egg PC for human use with an average diameter of 60 nm±5 nm in size, were prepared by extrusion using filtration through polycarbonate membrane filters using an Aviston EmulsiFlex-C50 homogenizer with Supor Cap™ and SuporDCF™ serial layer disposable filters (220 nm, 180 nm and 80 nm). These vesicles were empty SUVs.
[0113] Liposomal particle size was measured by Solvias AG, Basel, Switzerland submicron laser particle sizer, by Quasielectric light scattering or comparable method. It can also be determined using a Coulter model N4 sub-micron particle analyzer equipped with a size distribution processor analyzer (Barenholz et al. In Gregoriadis, G. (ed), LIPOSOME TECHNOLOGY, pp. 524-607, CRC Press, Boca Raton, Fla. (1993)). The final extrusion step was through a 0.08 μm pore polycarbonate membrane filter. Egg PC SUv's should be sterile, endotoxin (LAL)-free and pyr...
