FairJourney Bio opened a new cryo-electron microscopy (cryo-EM) structural biology facility in San Diego, upgrading its ability to generate atomic-resolution structures directly inside its antibody discovery workflow. The site includes a 300 kV cryo-EM infrastructure with two ThermoFisher Titan Krios 5 systems. The company says the facility supports native-state structure determination of antibody–target complexes and will feed decisions earlier in lead optimization, including epitope mapping and hit selection. FairJourney frames the move as shifting structural biology from late-stage confirmation to front-end design guidance. For the antibody discovery ecosystem, expanded cryo-EM capacity can shorten iteration cycles and may improve screening confidence when lead candidates depend on structural fit and binding-mode interpretation.
