Abstract
A method for recovering a desired virus type from a mixture of unwanted compounds places a mixture in a first sample chamber of an electrophoresis apparatus that contains a separation membrane located between the first sample chamber and a second sample chamber. Applying an electric potential across the first and second sample chambers separates at least a portion of one virus type on one side of the separation membrane while unwanted compounds are located on the other side of the separation membrane. Either the desired virus type or the unwanted molecules move through the separation membrane. The potential is applied until the required amount of desired virus type is located on one side of the separation membrane. Approximately 50% or more of the desired virus type that is located on one side of the separation membrane remains viable or substantially unchanged after recovery.
