  • Publication number: 20180066237
    Abstract: 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 and a predictable contaminant into the continuous flow centrifuge rotor; rotating the continuous flow centrifuge rotor in a manner sufficient to separate the viral vector from the predictable contaminant and the material in the nonionic density gradient; and unloading the separated viral vector from the continuous flow centrifuge rotor.

  • Patent number: 9050609
    Abstract: A centrifuge apparatus is provided that operates at certain predetermined parameters depending upon a product to be separated and is useable with a plurality of rotor assemblies. For example, a first rotor assembly of said plurality of rotor assemblies includes a first core having a first core configuration which is contained within a rotor housing of the first rotor assembly to define a first volume capacity such that the product passing through the first rotor assembly having the first volume capacity during rotation of the first rotor assembly in the centrifuge apparatus achieves a first particle separation of the product.
