Pharmacology Research Unit (URP)

The mass spectrometry platform of the Pharmacology Research Unit (URP) is a platform specialized in the monitoring assay of drug molecules and/or their metabolites in different biological matrices. This unit is part of the common scientific platforms of the Centre de recherche du CHU Sainte-Justine Research Center.

In January 2021, an integrated pharmacology platform, supported in part by the Centre de recherche du CHU Sainte-Justine was launched to assist researchers in pharmacometrics projects associated with clinical trials or for molecule dosing in translational research projects.

The platform has dedicated expert staff and state-of-the-art equipment such as tandem mass spectrometers (MS/MS) to assist researchers drug monitoring in a pediatric context of limited sampling volume.Staff have extensive experience in dosing components (e.g., ruxolitinib, trametinib, busulfan, cyclosporine, tacrolimus, isavuconazole, alpelisib, cephalexin ) and in the measurement of different parameters such AUC,  Cmax, Cmin and free fraction. URP team offers its full support to make this expertise available to research projects of the scientific community.
