mAb reactivity to different influenza virus strains in a cell-based ELISA. Binding profiles of six human mAbs against A/Netherlands/602/2009 (H1N1) (A), A/Hong Kong/4801/2014 (H3N2) (B), and B/Colorado/06/2017 (C) viruses measured by ELISA. CR9114, a cross-reactive influenza virus HA stem binding mAb, was used as a positive control. 1D04, an anti-CHIKV E1 glycoprotein mAb, was used as a negative control. For all panels, OD₄₅₀ values are shown. The non-linear regression for each group is indicated. Data are representative of one experiment with duplicate measurements.
