Fig. 1: Breadth of FNI9, FNI17 and FNI19 anti-NA mAbs across IAVs and IBVs.
From: A pan-influenza antibody inhibiting neuraminidase via receptor mimicry

a, Phylogenetic tree of IAV and IBV NAs constructed using maximum likelihood analysis of amino acid sequences. The scale bar indicates the average number of amino acid substitutions per site. b, Heat map of mAb binding to cell-surface-expressed NAs representative of IAV and IBV strains by flow cytometry. Coloured boxes represent the lowest concentration at which mAb binding (expressed as mean fluorescence intensity) was measurable.
