Protecting Critical Virus Filtration
Pegasus Protect virus prefiltration combines with Pegasus Prime virus filtration to deliver the first gamma-sterilized pre-filter & virus filter combination. Together, these simplify process development, validation and operations while saving time and delivering improved process economy.
Process developers can quickly deliver a robust, scalable virus filtration process using a minimum of sample volume, and be confident of successful virus validation. This choice supports clinical manufacturing with a solution that is easy to use and versatile to work alone or with integrated and automated single-use systems.
Both gamma irradiated and non-irradiated Microdisc capsules containing Pegasus Protect media are optimized for the confirmation and validation of performance at a small scale using minimal volumes of process fluid.
Performance established during small scale trials can be easily scaled as both Pegasus Protect prefilters and Pegasus Prime virus filters are available in a range of optimized capsule and filter formats which maintain a constant area ratio between prefiltration and virus filtration at all scales.
All process scale devices can be integrated into single-use and automated solutions to offer the highest degree of control, flexibility and security.

Impact of Pegasus Protect Prefiltration on Required Virus Flters Per Batch

Scalable Solutions
Prefiltration area and flowrate are critical variables that may affect the performance of Pegasus Protect prefiltration and Pegasus Prime virus removal filters when used in combination.
To control these variables Pegasus Protect prefiltration media is available in a range of formats, designed to maintain a consistent pre-filter to virus-filter ratio. This control ensures predictable and consistent performance at all scales from the initial Microdisc scale trials to clinical manufacturing.
