Abstract: Described herein is a rapid continuous biomanufacturing platform process that combines a perfusion mammalian cell culture with a synchronized purification of the antibodies produced by the cell culture without the use of intermediate media holding tanks or other large retention devices. This method described herein includes continuous cell culture of mammalian cells expressing the biological of interest and comprising a cell retention device wherein the perfusion of fresh media into the reactor and hence the harvest rate of antibody containing spent media from the reactor has a rate of 1 vessel volume per day (vvd) or less obtained by glucose control with a cell density of between 40 million cell/ml and 60 million cell/nil. Immediate recovery and purification of the antibody is obtained by synchronizing the rate of perfusion with the antibody capture and elution step cycle in a column that contains affinity resin that is between 0.01 and 0.001 times the volume of the bioreactor.

Abstract: A carrier system for the delivery of therapeutic and/or diagnostic agents is described. The carrier system is comprised of ligands and a biodegradable polycation for complexing polyanionic molecules such as RNAi, said polycation forming a coating on the outer surface of anionic or neutral liposomes. Also disclosed is a method for using the composition to deliver to target cells and enhance cell membrane penetration of therapeutic and/or diagnostic agents.
