Fig. 1: Two high-affinity nanobodies bind non-overlapping epitopes.

a Purified nanobodies were assessed by SDS-PAGE. b, c Binding kinetics of the nanobodies (Nb) were obtained with BLI using biosensors loaded with nApi m 1. b Kinetic constants were calculated using a 1:1 binding model (black lines). c Simultaneously binding was assessed by binding of AM1-1 (green) followed by binding of AM1-4 (blue) (left) or vice versa (right).
