About Toxys

Toxys is a Dutch biotech company that develops and provides innovative in vitro solutions for safety testing of novel pharmaceutical compounds, chemicals and materials. Our stem cell-based reporter systems are designed to rapidly identify hazardous and potential carcinogenic properties of novel compounds during the early phases of product and drug development. Toxys exclusively offers ToxTracker, a unique reporter assay for carcinogenicity hazard identification with unsurpassed sensitivity and specificity that has the important advantage that it provides insight into the underlying mechanisms of toxicity.

We are currently expanding our portfolio with a novel stem cell-based reporter system for developmental toxicity. Our unique ReproTracker assay combines the expertise at Toxys on stem cells, genome editing and mechanistic toxicity screening and is aimed to rapidly identify compounds that disturb stem cell differentiation and early embryonic development.

 We always aim to closely collaborate with our customers to provide them with the necessary information to make decisions on which compounds to progress in the drug development pipeline, thereby contributing to the development of better medicines and products. In addition, by developing advanced in vitro test systems, Toxys contributes to the reduction of animal testing. To support our ambitions in these fields, we are expanding our team.
