About Us

We aid the transition from animal-based to in-vitro human-based pyrogen testing to increase patient safety and save animal lives.

To achieve this, we’ve been developing the Monocyte Activation Test (MAT) since 2016.

Our Vision

We fully support the decision taken by the European Pharmacopoeia (Ph. Eur.) to completely replace the rabbit pyrogen test (RPT) with the monocyte activation test (MAT) before 2026.

The MAT has been developed for nearly 50 years, but there has been a lack of public awareness around this topic. With the new course of the EDQM, we can finally push for the implementation of the MAT as the new standard testing method for pyrogens.

Fleur de Roos

Research Associate & Lab Manager

Gaining a solid basis in chemistry during her study, Fleur moved more towards biochemistry. During an internship abroad, further interest was sparked in the startup environment as well as animal-free solutions. Therefore, the challenge to streamline production and further develop the MAT test is right up her lane.
