Robust Parvovirus Clearance
High LRV Performance
The Viresolve® Pro Devices are designed and validated to deliver:
• ≥ 4.0 logs of clearance of Minute Virus of Mice (18–24 nm)
• ≥ 5.0 logs of clearance of x-Murine Leukemia Virus (80–110 nm)
Figure 1 provides an example of high and robust MMV retention performance achieved with Viresolve® Pro Micro Devices with two mAb solutions at various flow decay points. Following addition of a 1% v/v MMV virus spike, feed solution was filtered through a 0.22 µm filter. Flow rates and flow decay points were determined relative to the initial buffer flux rates (J0), which were corrected for temperature based on the mAb and buffer temperatures at the end of the run. The LRV was determined as shown in the calculation below:
v1 and t1: input volume (mL) and virus titer (TCID50/mL) v2 and t2: output volume (mL) and virus titer (TCID50/mL)
As can be seen from the results, the Viresolve® Pro Solution achieved MMV pool LRV of ≥ 6.0 for mAb 1 solution and ≥ 5.2 for mAb 2 solution. There was no virus detected in the filtrate for any of the devices. Results obtained with mAb 2 demonstrate robust virus clearance; even at 90% flow decay, no passage of MMV was observed (mAb 1 experiment was limited to 70% flow decay due to limited volume of solution available).
These results demonstrate high and robust virus clearance performance of Viresolve® Pro Devices across a range of flow decay points.
Enhanced Process Robustness
For challenging feed streams that require greater process robustness due to feed stream impurities, the Viresolve® Pro Shield or Viresolve® Pro Shield H can be combined with the Viresolve® Pro Device. The Viresolve® Pro Shield and Viresolve® Pro Shield H adsorptively remove impurities and other potential foulants that can plug the Viresolve® Pro Device and lead to decreased capacity. Figure 2 illustrates the optimal performance of the Viresolve® Pro Shield and Shield H, depending upon the feed stream characteristics.
The Viresolve® Pro Shield or Viresolve® Pro Shield H combined with the Viresolve® Pro Device also limits the process optimization required so that it is easy to incorporate into any template.

High Performance AssuranceUnique performance tests that form a solid foundation for virus clearance assurance and regulatory compliance are performed on the Viresolve® Pro Device. These tests are built into every level of Viresolve® Pro Device production, including testing of membrane, device lot release, and, 100% device testing. The tests were developed and validated to ensure they are relevant and representative of the virus filtration application, and that they are sensitive enough to assure robust LRV performance.
Building Quality We employ a 5-tier approach to assuring virus retention and integrity of Viresolve® Pro Devices.
Tier 5 End-User Validation and Testing
• Virus Filter Validation, 100% Pre-Use and Post-Use Diffusion Test
Tier 4 Devices Tested 100%
• Pressure Hold, Water Flow Rate, Air/Water Diffusion and Binary Gas Test
• ΦX174 LRV at V75, Protein Capacity and Flux (IgG)
Tier 1 Process and Product Validation
• Scaling, MMV Virus Retention, Caustic Stability, Shelf Life, etc.
• Process Design Space Validation
Innovative Binary Gas TestOne example of the extensive testing performed on the Viresolve® Pro Devices is the patented Binary Gas Test (BGT). This proprietary device integrity test uses a mixture of two gases selected in part for their high differences in permeability. This test is based on measurement of the composition of the gas mixture upstream and downstream of a water-wetted device (Figure 3).
The benefit of BGT is its ability to detect defects as small as 3–5 microns that cannot be detected using a traditional air/water diffusion test. This high sensitivity is especially valuable for high-retention devices like Viresolve® Pro Devices, as can be seen from the theoretical model (Figure 4A). In this example, a defect in the 3–5 micron range can have a significant (> 0.5 logs) negative impact on the inherent virus retention performance of a virus filter. These theoretical predictions are consistent with data that we have generated (Figure 4B). While devices 1, 2, and 3 look the same (based on the air/water diffusion measurement), there is a 10x difference between the BGT test for devices 2 and 3. The increased BGT value for device 3 would indicate a defect that decreased the inherent retention capabilities of the membrane, in this case, approximately 0.9 logs and, therefore, would not be released. As part of our quality control process, only devices that pass the BGT are released for shipment.
Enables High Productivity Viral Clearance Unit Operation
High Capacity and Flux
The Viresolve® Pro Solution allows for the processing of high-concentration feed streams that are becoming more common with the recent improvements in bioreactor productivity and advancements in other downstream processing technologies. The Viresolve® Pro Shield or Viresolve® Pro Shield H can enhance the throughput and processing robustness of Viresolve® Pro Devices for feed streams that are capacity limited. For the Viresolve® Pro Solution, 5–10 kg/m2 mass capacity for mAbs in the 5–10 g/L concentration range was targeted. In addition to high mass capacity, the Viresolve® Pro Solution was designed to deliver mass flux in the 1,250 to 2,500 g/m2/h range, enabling processing times of 4 hours or less.
We have performed extensive testing with a range of proteins. Figure 5 shows results generated with 16 proteins (concentrations from 2.5 to 25 g/L). Viresolve® Pro Devices achieved 7.0 kg/m2 on average (n=16; capacity based on a 4-hour process time limited to 75% flow decay using buffer flux as the initial flux).

Virus Filtration Process Development and Service
Producing protein at the lowest cost per gram requires that you design and implement a consistent, well-defined virus strategy and optimization process. Achieving these goals also saves you time and materials and maximizes product recovery. Optimizing a virus filtration process involves evaluating the effect of a variety of process parameters to arrive at conditions that will ensure a robust, consistent, economical, and scalable operation. For more than 20 years, we have been working side-by-side with industry-leading researchers and manufacturers, helping them achieve the lowest possible cost for unit operations by successfully tackling some of the same challenges you are facing.
We can help you achieve your goals at every step of the virus clearance operation by working with you to:
• Minimize your processing time
• Maximize product recovery
• Maximize your LRV
Viral Clearance Service
Virus validation/spiking studies are required by regulatory agencies. At different milestones along product development phases, demonstration of viral clearance in your process is required. Retrovirus removal or inactivation should occur prior to Phase 1 studies.
The optimal virus validation study results in:
• Optimal capacity and LRV targets
• The option for a properly sized manufacturing system
• A submission-ready GMP report
All of these have direct impact on the long-term results of your manufacturing process.
Virus Filter Implementation Service
After successful virus validation, operating parameters selected and optimized at bench scale must be scaled and implemented at manufacturing scale. Less-than-optimal implementation can have economic consequences, particularly at manufacturing scale.
Our engineers will implement your pilot or manufacturing scale virus filtration process using appropriate scaling rules and data obtained during bench scale optimization studies.
Partner with a leader in viral clearancePharmaceutical manufacturers are required to validate the effectiveness of virus clearance steps and document the adequacy of the manufacturing process to achieve an appropriate level of virus safety. The validation approach is generally modeled after current regulatory guidance.
Our strong relationship with regulators worldwide allows us to develop products and services designed to help you meet or exceed regulatory requirements.
