Bioanalysis for Biologics

Peptides, monoclonal antibodies (mAb), multi-domain antibodies, antibody-drug conjugates (ADC), biosimilars, and traditional and next-generation oligonucleotides – Charles River scientists are global leaders in this rapidly growing and evolving field.

Ligand binding assay bioanalysis is not an independent discipline; our scientists work closely with our immunogenicity, pharmacokinetic, and statistical specialists to deliver the pertinent solutions and interpretations applicable to your molecule and your study.
