We are dedicated to bringing relevant information to our clients on potential human health hazards of novel and existing drugs, chemicals and other substances. Toxys is currently working with 7 of the Top10 global Pharma companies and several major chemical, cosmetics and food multinationals.

Toxys has developed the unique ToxTracker® and ReproTracker® assays. ToxTracker is a high-throughput stem cell-based reporter suite of assays that allows reliable identification of genotoxic carcinogens. ToxTracker provides mechanistic insight into undesired properties of chemicals. ReproTracker® is currently under development and its commercial launch (planned for early 2020) will allow in vitro developmental toxicity hazard identification. These assays can be particularly useful in Mode-of-Action and Adverse Outcome Pathway (AOP) approaches for chemical safety assessment. 

We offer ToxTracker and ReproTracker as tailored service to our customers, often in combination with standard toxicology assays or under license and as kits for use in partner’s own laboratories. Toxys is highly valued for its scientific expertise, high quality results and responsiveness.
