摘要:
What is described is a method for preparing a liposome that efficiently encapsulates a negatively charged therapeutic polymer, e.g., siRNA. The process involves preparing a lipid mixture comprising a cationic lipid in a water miscible organic solvent such as ethanol, and injecting this solution to the polymer dissolved in water to a final concentration of 35% ethanol in water to produce nanoparticles having a mean size of 50 to 150 nm and a final charge ratio of drug:lipid is 1 :2.5.
