Robust Virus Retention with Pressure Interruptions
Virus filtration is a vital part of the viral clearance strategy in bioprocesses. In filtration, size exclusion mechanisms are orthogonal to other inactivation or removal techniques and target the physical dimensions of the virus to achieve a high degree of virus reduction. Any flow or pressure interruption during filtration has been shown to increase the risk of virus passage. This application note reviews the Pegasus™ Prime virus removal filters and demonstrates robust, high viral clearance in the presence of prolonged pressure interruptions.
