Abstract
Tangential flow filtration is used in the size separation of particles, such as liposomes and lipid particles. These particles may be passed through a tangential flow filtration device of any pore size desired. Tangential flow filter systems of various pore sizes may be used sequentially to obtain particles such as lipid particles or liposomes having a defined size range.
