UNLOCK YOUR DRUG DISCOVERY

At Cell Origins, we understand that peptide and antibody discovery can be a challenge. To help overcome these challenges, we are dedicated to providing high-quality phage display libraries that are rigorously controlled to obtain the lowest rate of stop codons and other unintended sequences.

We specialize in high-quality, customizable peptide phage display libraries, delivering cutting-edge solutions for therapeutic and diagnostic discovery. Peptides are a powerful and versatile class of molecules with proven success in targeting biomarkers for disease treatment and imaging.

PREMIER PEPTIDE LIBRARIES BACKED BY NOBEL PRIZE-WINNING SCIENCE

We offer ready-to-use linear and cyclic peptide libraries based on the pioneering f3TR1, fUSE5, and f88-4 phage display vectors developed by Nobel Laureate Dr. George Smith, the founder of phage display technology. Our libraries are engineered for exceptional diversity, validated quality, and optimized performance in drug discovery and molecular targeting applications.

CUSTOM PHAGE DISPLAY LIBRARIES & EXPERT SUPPORT

Need a phage display library that's more tailored? Our custom peptide and antibody libraries are built with your exact needs in mind. We offer:

• Vector customization for peptide or antibody display.
• Post-selection features like biotinylation, soluble ligand expression, and affinity capture.
• Expert support to help design, optimize, and execute your phage display strategy.

Our team works closely with you to develop advanced, application-specific phage display libraries that maximize success in selection, screening, and downstream development.
