SERVICES

Premier Phage Display Services

Cell Origins provides critical peptide and antibody drug discovery services. Hailing from the birthplace of phage display, our scientists have extensive experience implementing customized phage display strategies. We understand that each project is unique and we tailor every project based on our multi-tiered approach.

Phage Display Libraries

At Cell Origins, we understand that peptide and monoclonal antibody discovery can be a challenge. To meet your needs in drug discovery, we carry premade linear and cyclic peptide phage display libraries as well as customized peptide and monoclonal antibody libraries of unmatched high quality and diversity.

Affinity Selections

We understand that each affinity selection is unique and tailor each project to its specific needs. We begin with gaining in-depth knowledge of your target to design a customized biopanning strategy. Our unique multi-tiered approach yields peptides and antibodies with high binding affinity and optimal pharmacokinetics.

Screening

We understand that accurately capturing biomolecular interactions in the lab is challenging. We overcome these challenges by developing a customized protocol for each screening procedure. We use advanced high-throughput methods including our own novel screening approach with high sensitivity.

Consulting

Our expertise in the development of cutting-edge strategies for phage display peptide and antibody discovery spans over 30 years. Our wide range of consultancy services provides comprehensive support regarding affinity selections, peptide and antibody screening, affinity maturation, and more.
