The Sterways process: a new approach to inactivating viruses using gamma radiation
1Gamma Irradiation, Sterways Pioneer Inc., Suite 2001 130 Albert Street, Ottawa, ON K1P 5G4, Canada.
Summary
The Sterways process uses controlled gamma radiation to sterilize and inactivate viruses in blood products. This method ensures maximum viral kill while minimizing product loss, protecting against known and emerging viral threats.
Area of Science:
- Biotechnology
- Radiation Sterilization
- Blood Product Safety
Background:
- Blood products require terminal sterilization to ensure patient safety.
- Viral contamination poses a significant risk to recipients of blood products.
- Existing sterilization methods may lead to product degradation or insufficient viral inactivation.
Purpose of the Study:
- To introduce and describe the Sterways process for terminal sterilization and viral inactivation of blood products.
- To highlight the controlled application of gamma radiation for optimizing viral kill and minimizing product loss.
- To emphasize the broad-spectrum efficacy against known, emerging, and novel viruses.
Main Methods:
- Utilizing gamma radiation as the sterilization agent.
- Implementing a controlled dose rate specific to product formulation.
- Applying the Sterways process for terminal sterilization.
Main Results:
- Achieved terminal sterilization of blood products.
- Demonstrated effective viral inactivation, including broad-spectrum efficacy.
- Minimized product loss through controlled radiation parameters.
Conclusions:
- The Sterways process offers an effective method for sterilizing and virally inactivating blood products.
- Controlled gamma radiation provides a balance between high viral efficacy and product integrity.
- This process enhances the safety of blood products against a range of viral agents.
