Methods and devices for producing a population of liposomes are provided. Aspects of the methods include applying a centrifugal force to a suspension of liposomes in a manner sufficient to pass the liposomes through a porous membrane to produce a population of liposomes. Aspects of the invention further include devices, systems and kits useful for performing the methods.

Provided is an improved filtration module assembly comprising a vessel having a filtration cartridge disposed within it and a header coupled to an end of the vessel, the header including a housing having an open-ended upper end and a lower end, and an end cap including a portion that mates with a complimentary structure defined by the inner all of the open ended upper end of the housing to removable engage with the housing and the end cap may further define a passageway for fluid to flow out of the vessel. The filtration module assembly may enable an improved manifold arrangement used to communicate fluids to and from a filtration system comprising a plurality of such modules and the configurations of the present invention may facilitate improved operation of such filtration systems.

Provided is a method for producing and/or purifying measles virus (MV) particles from a sample, the method comprising in sequential order the following steps loading a sample containing MV particles and one or more impurities onto a stationary phase material for carrying out flow-through chromatography to bind at least a fraction of the impurities contained in the sample and to produce a flow-through comprising at least a fraction of the MV particles contained in the sample; carrying out filtration, preferably ultrafiltration, and obtaining a retentate having an increased MV titer relative to the MV titer comprised in the flow-through. Further provided is a system for producing and/or purifying MV particles, comprising at least one bioreactor; a clarification unit, preferably a dead end filter unit, downstream to the bioreactor; a flow through chromatography unit downstream to the clarification unit; and a filtration unit, downstream to the flow through chromatography unit.
