Upscaling of lentiviral vector production by tangential flow filtration

Abstract

With this new standardized method for lentiviral vector production and concentration, 1 ml of concentrated vector is routinely produced with titers of 10(9)-10(10) TU/ml starting from 2 l of cell-culture medium. Moreover, stereotactic injection of this vector in mouse striatum resulted in a large transduced brain volume in the absence of any immune response.
