Cryo-EM Structural Biology Facility Opened in San Diego by FairJourney Bio

FairJourney Bio (FJBio), a CRO, opened its advanced cryo-electron microscopy (cryo-EM) structural biology facility in San Diego. The new site significantly expands the company’s presence in the U.S. market and incorporates atomic-resolution structural biology directly into its antibody discovery platform, according to Christopher Arthur, PhD, CSO, structural biology, FairJourney Bio.

The facility houses a 300 kV cryo-EM infrastructure, including two ThermoFisher Titan Krios 5 systems, which enables native-state structure determination of antibody-target complexes. The technology is designed to provide detailed insights across the R&D value chain—from epitope mapping and hit generation to structure-guided lead optimization and candidate selection.

The cryo-EM services, launched in January 2026, complement FJBio’s antibody discovery and biologic development portfolio. The services enable scientists to visualize protein structures at atomic resolution, including protein-protein and protein-ligand complexes, providing high-quality and interpretable results to inform confident decision-making across programs.

The facility is strategically positioned within a leading global biotech hub, complementing FJBio’s existing U.S. presence in San Francisco and its operations across Europe.

“Structural biology has historically been a late-stage tool, used to confirm decisions already made,” notes Arthur. “We are redefining that paradigm. In San Diego, we are building a premier, full-service cryo-EM CRO that brings together decades of deep expertise in sample preparation, data collection, and computational analysis, embedding structural insight at the very start of discovery, where it shapes epitope selection and determines which leads are worth advancing.”
