Figure Lengend Snippet: Epitope binning analysis informs on mAb combinations that optimally avoid the induction of viral antibody escape variants. a) Pairwise competition measurement using SPR. b) Epitope binning from pairwise competition measurement. Blue colour symbolises the ability of a mAb pair to bind the antigen simultaneously, red colour indicates competition of a mAb pair for their epitope on the antigen. c) Virus escape assay using VSV∗ΔG-S in presence of the mAb cocktail MB021_C09K and MB025_A09L. d) Dose-dependent measurement of Fc-mediated effector functions (Antibody-dependent complement deposition [ADCD], cellular phagocytosis [ADCP], neutrophil phagocytosis [ADNP], and NK cell activation [ADNKA]) for the six mAbs in the epitope binning analysis. e) Effect of cocktail formulation on the Fc-mediated effector functions.
