Binding and aggregation characterization of different format anti-hNE antibodies. (a) VH 1D1.43, Fab 1C10, VH-Fc 1D1.43, and IgG1 1C10 binding to recombinant NE measured by ELISA. Experiments were performed in duplicate. (b) Aggregation evaluation of VH 1D1, VH 1D1.43, and VH-Fc 1D1.43 measured by SEC. (c) Aggregation evaluation of Fab 1C10 and IgG1 measured by SEC. (d) Aggregation evaluation of VH and Fab measured by DLS. Antibodies were evaluated at a concentration of 1 mg/mL. (e,f) Kinetics of VH-Fc 1D1.43 (e) and IgG1 1C10 (f) binding to recombinant NE measured by BLItz. Values were reported as the mean ± SD.
