Our Sites
We have a number of sites in the UK and Europe. Click on each below to find out about the history of each site and what we do.

CRL Leiden is conveniently located nearby the center of Leiden, in the largest life science cluster of the Netherlands: Leiden Bio Science Park. From the Leiden facility we offer clients access to (high throughput) phenotypic screening in human (primary) cell based assays. We are well equipped to perform the development and/or optimization of basic and more complex cell biological or biochemical assays.

CRL Beerse was founded in October 2017 and is located on the campus of Janssen Pharmaceutica in Beerse, Belgium. As part of Johnson & Johnson, Janssen Pharmaceutica focuses its research on six pathological areas: oncology, neurosciences, infectious diseases and vaccines, immunology, cardiovascular and metabolic disorders and pulmonary hypertension.
