Screening Biomarkers

Biomarker assays and analytical readouts are important tools in drug discovery from target validation studies to candidate selection, so the ability to measure with accuracy and sensitivity is essential in making critical go/no-go study decisions. With years of experience in assay design and sample processing, Charles River can support your drug discovery pipeline by providing biomarker analysis in a non-GxP environment.

Whether your study is performed at your facility or designed and implemented at ours, our focus on strategic assay validation/qualification enables us to accurately test your study samples and provide reliable biological translation to your drug discovery program.

Charles River offers a wide range of study-specific analytical services using platforms such as Meso Scale Discovery (MSD®), Luminex®, ELISA, EIA, Western blotting and HPLC. Assays include, but are not limited to:
