Phage Display


Talk to a Scientist

ChemPartner’s phage display and high throughput screening group offers streamlined services for fully human therapeutic antibody discovery and optimization, also providing coherent protein engineering, immune library construction, and screening for general biologics development. Supported by our strong analytical capabilities and infrastructures in pharmacology, DMPK, and toxicology, we are well-positioned to provide globally competitive services with significant cost reduction.
