Discover the Power of Phage Display

Cell Origins offers products to support each step of your phage display journey. We carry pre-made and custom peptide and antibody phage display libraries, bacteriophage and phagemid vectors, helper phage, and select E. coli strains. Please contact us to inquire about custom products.

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 libraries as well as customized peptide and antibody libraries of unmatched high quality and diversity.

Vectors

Cell Origins offers bacteriophage and phagemid vectors that are based on the pioneering work of Nobel prize winner, Dr. George P. Smith. Many of our vectors include convenient tagging options, streamlining both phage display affinity selections (biopanning) and subsequent screening procedures.

Bacterial Strains

We understand the importance of amplifying stable libraries without losing ligand expression or library diversity. Cell Origins provides E. coli strains and detailed protocols for the most optimal amplification of peptide and monoclonal antibody phage display libraries using phagemid or bacteriophage vectors.

Helper Phage

Coming soon! Helper phage are required to produce phage particles when using phagemid-based vectors. We provide helper phage and detailed protocols for straightforward amplification of phagemid peptide and antibody libraries and the production of phage particles in E. coli.
