What people are saying

Reaction Biology Europe has provided their services for several projects with us, including establishing an orthotopic tumor model and PK/PD studies. I was very impressed, not only by their level of expertise and professionalism but also by their enthusiasm and drive to deliver. The insightful advice they provide has been instrumental to our successes and their collegial and “can do” attitude make them a pleasure to team up with!

Prof Matthias Klugmann
Scientific Expert at Boehringer-Ingelheim

I have worked with Reaction Biology Europe and Reaction Biology Corp. for more than 5 years on several interesting projects. These have ranged from routine enzyme screening to more complex kinome-scan and in-cell target engagement work. The results of these endeavors have led to a series of top-tier publications. This coupled with exceptional customer service means I have no hesitation to recommend Reaction Biology Corp. and Reaction Biology Europe as research partners.

Dr Christopher Asquith
Department of Pharmacology, School of Medicine, University of North Carolina at Chapel Hill

Reaction Biology Europe has provided their service for numerous projects with us, especially on multiple kinase assays (under the name ProQinase) which have guided our way through drug development. I was very impressed not only by their level of expertise and professionalism but also by their enthusiasm and drive to deliver without delay. The insightful advice they provide has been instrumental to our successes, and the reproducibility, quality, and reporting of the results have been outstanding throughout the many years we have been working together.

Dr Laurent Meijer
Chair & Chief Scientific Officer at Perha Pharmaceuticals & ManRos Therapeutics

We have worked with Reaction Biology Europe for 3 years on in vivo drug development assays. They have provided their services from routine PK through efficacy and custom BLI studies in tumor models, consistently generating high-quality results that guided our development process. Their expertise, responsiveness, and professionalism make Reaction Biology stand out from among the usual CROs, and we are happy to recommend them as research partners.

Dr Oliver Thorn-Seshold
Department of Pharmacy, Ludwig-Maximilian's University of Munich (LMU)

We have founded two companies for drug discovery in extremely challenging sectors - epitranscriptomics and phosphatase biology. For both projects we have partnered with Reaction Biology. Tackling drug discovery projects that are based on novel and rapidly evolving science requires a CRO with profound know-how and a specific mindset - a focus on customers, the ability to think out of the box, and the capability to provide highly customized screening and assay solutions. We found all that in our relationship with Reaction Biology.
