FairJourney Bio opened a cryo-electron microscopy (cryo-EM) structural biology facility in San Diego, expanding the company’s U.S. presence and adding atomic-resolution structure capability directly into its antibody discovery platform. The site includes a 300 kV cryo-EM infrastructure with two ThermoFisher Titan Krios 5 systems. The company says it uses native-state structure determination to support epitope mapping, hit generation, structure-guided lead optimization, and candidate selection. By shifting structural biology earlier in the discovery workflow, FairJourney aims to shorten iteration cycles and improve decision quality for antibody programs. For CRO and platform players, the facility buildout signals continued demand for high-end structural characterization in therapeutic biologics development, particularly for teams trying to de-risk lead selection. With services launched in January 2026, the San Diego expansion positions the company closer to a major biotech talent and client base.
