  • Liposome extrusion process
    Patent number: 6623671
    Abstract: A method of sizing liposomes by passing a suspension of liposomes through an aluminum oxide porous film by entering the film via the smaller pores and extruded via the larger pores, under pressure, is disclosed. In a preferred embodiment, the porous film is a branched-pore type anodic aluminum oxide porous film. The process produces a population of liposomes substantially free of liposomes above a predetermined maximum size. Also disclosed is an apparatus for carrying out the invention.
    Type: Grant
