Abstract

See full text

A method of purifying a viral vector is provided. The method includes loading a nonionic density gradient into a continuous flow centrifuge rotor; loading a material including the viral vector into the continuous flow centrifuge rotor; rotating the continuous flow centrifuge rotor in a manner sufficient to separate the viral vector and a predictable contaminate from the material in the nonionic density gradient; and unloading the separated viral vector and the predicable contaminant from the continuous flow centrifuge rotor.
