LENTIVIRAL VECTOR MANUFACTURING PROCESS IN PACKED BED BIOREACTOR

摘要

The present invention relates to the development of a method for the manufacturing of LVV vectors in a packed bed bioreactor by multi-plasmid transient DNA transfection. More particularly, the present invention discloses and claims a process in which steps applied in perfusion or in batch mode are combined to obtain an effective process. Moreover, the invention identifies an effective range of total DNA to be successfully used in the step of transient transfection in a packed bed bioreactor for the manufacturing of lentiviral vectors.
