Bioanalysis at ChemPartner

ChemPartner offers comprehensive discovery and regulated bioanalysis services, combining a high-performance mass spectrometry platform for small molecules, peptides, oligonucleotides, and proteins with a dedicated ELISA/MSD laboratory for large molecule analysis. Underpinned by GLP/GCLP compliance and Watson-LIMS integration, our laboratory is equipped to manage clinical samples with full traceability and data integrity. 

Small Molecule & Biomarker Bioanalysis 
Our team delivers high-quality qualitative and quantitative analysis of drugs, metabolites, and biomarkers across complex biological matrices. Using LC-MS/MS as a core analytical approach, we support in vitro ADME, biology, pharmacology, PK, and PK/PD studies across a broad range of modalities — including small molecules, PROTACs, peptides, oligonucleotides, ADCs/AOCs, and PDCs. 

Our instrument portfolio includes the API 7500/6500/5500, Q Exactive Orbitrap, and G2-S QTOF, with over 48 MS systems in total. We develop more than 20,000 methods annually in support of discovery and biomarker programmes. For regulated studies, we adhere strictly to FDA, EMA, NMPA, and ICH guidelines, and provide robust toxicokinetic analysis for GLP safety assessments. 

Large Molecule & Biomarker Bioanalysis 
Our PK, bioanalysis, immunology, and biomarker scientists bring deep expertise across the full spectrum of large-molecule therapeutics — from conventional monoclonal, bispecific, and trispecific antibodies to complex modalities including ADCs, PDCs, AOCs, and proTCEs. We have extensive experience navigating the analytical challenges unique to these modalities, including drug tolerance, target interference, and matrix complexity, working in close partnership with pharma and biotech clients to address even the most demanding targets. 

Our large-molecule PK/bioanalysis services are designed to accelerate drug development programmes at every stage, from preclinical through to clinical. Built on rigorous method development and validation, and fully compliant with NMPA, FDA, EMA, and ICH guidelines, our workflows deliver high-quality, reproducible data that teams can rely on to advance their candidates with confidence.”
