Fig. 6: Structural details of four XGi bbAbs complexed with Omicron EG.5.1 S trimer.

a–h Cryo-EM structures of EG.5.1 S trimer in complex with four XGi bbAbs, and their hydrogen bond interactions or salt bridges. Tested mAbs include XGi-183 (a, b), XGi-203 (c, d), XGi-171 (e, f), and XGi-198 (g, h). The hydrogen bond interactions or salt bridges are illustrated as dotted lines. i Epitopes of XGi-183, XGi-203 and XGi-171 on the EG.5.1 RBD.
