Binding traces for each spike protein in the qualification panel against the two test antibodies. Spike proteins were loaded on the biosensor tips. Indicated concentrations refer to either tixagevimab (left) or cilgavimab (right) in the association phase for each spike protein. The association phase was 180 s, followed by a 600-s dissociation phase. Binding is represented by wavelength shift (Δλ; measured in nanometers [nm]) as detected by the Octet instrument.
