A Proactive Approach to Blood Safety
Targeting DNA and RNA to Prevent Pathogen Proliferation
The INTERCEPT® System uses amotosalen – a well characterized photoactive compound that specifically targets DNA and RNA – and UVA illumination to irreversibly cross-link nucleic acids. In doing so, the INTERCEPT treatment blocks replication of viruses, bacteria, and parasites, rendering them inactive.1
Mechanism of Action
- Amotosalen targets nucleic acids, and intercalates or “docks” between nucleic acid base pairs.
- UVA illumination activates amotosalen, causing permanent cross-links between the helical strands.
- Cross-linking prevents further replication and inactivates the pathogen and/or leukocyte.
