Pegasus™ SV4 Virus Removal Filter Cartridges

Constant, stable flow-rate performance filters combining efficient, high viral clearance with significantly-reduced processing costs

With the ever-present risk of virus contamination in biologic products, potential sources of virus contamination of bio - technology products include viruses associated with cell lines (endogenous viruses), or viruses introduced into the cell line or product from culture medium or during the production process (adventitious viruses). Viruses could also potentially be present in donations for plasma derivatives. Pegasus SV4 Virus Removal Filter Cartridges are direct flow filters combining robust, high viral clearance of parvovirus and larger viruses with high throughput capacity and demonstrating constant, stable flow-rates in both dilute and complex/concentrated biological fluids. Such consistent, constant flow rates and outstanding throughput performance allows a very high degree of process control.

Performance

High Parvovirus Clearance

Pegasus SV4 Virus Removal Filter Cartridges demonstrate highly-efficient clearance of both small ‘non-enveloped’ viruses as well as large viruses. Figure 1 provides an example of its high parvovirus clearance by showing the typical performance of a Pegasus SV4 filter in a 1 g.L-1BSA solution, as per the PDA’s guidelines:

Figure 1

Due to its resistance to flux decay and outstanding throughput properties, typical spikes will not have significant impact on the flux decay of Pegasus SV4 Virus Removal Filter Cartridges.

Constant, Stable Flow-Rate Performance with Outstanding Throughput Capacity

With the need to control the Cost Of Goods Sold being one of the main points of consideration in downstream processing, Pegasus SV4 Virus Removal Filter membrane has been designed to address this need by offering constant, stable flow-rate performance and outstanding throughput capacity, thereby improving process and cost control and enabling maximum virus filtration economy and efficiency.

Highly-Efficient and Economical

Pegasus SV4 Virus Filter membrane also demonstrates highlyefficient clearance of both small ‘non-enveloped’ viruses and large viruses, even showing constant, stable flow-rate performance when used with dilute or complex/concentrated biological fluids. It also offers stable pressure/flux capability in more complex or concentrated feeds, helping to improve virus filtration economy in highly-concentrated protein solutions. Figure 2 shows a typical flux profile for Pegasus SV4 Virus Removal Filter Cartridges when challenged with a monoclonal antibody solution.

Reduces Processing Costs

Pegasus SV4 Virus Removal Filter Cartridges offer a very high filter area per cartridge (2.25 m2) due to their unique, patented laidover pleat construction which enables significantly more filter membrane to be packed into each cartridge. This helps to maximize process productivity while minimizing process costs, by reducing the amount of filter cartridges required per installation, and helps minimize the hold-up volume of the virus filter system.

Full Traceability, Fast and Efficient Data Entry

Each Pegasus SV4 Virus Removal Filter Cartridge is manufactured under a Quality Management System certified to ISO 9001:2008, and is easily identified by part number, lot number and a unique serial number, which are laser-marked on the filter cartridge as a two-dimensional (2D) barcode. These codes can be read by a barcode reader, enabling complete traceability of the manufacturing history.
