Binding and neutralizing activity of mouse anti-IFN-γ mAbs against IFN-γ. (A) The binding activity of the mouse mAbs was determined by indirect ELISA in triplicate. Error bars represent the mean ± SEM. (B,C) Neutralizing activity of the mouse anti-IFN-γ mAbs was assessed by a cell-based assay. THP-1 cells were treated with IFN-γ in the presence or absence of each mAb. The surface MHC-II expression was evaluated by flow cytometry, and the stimulation index was determined by calculating the stimulated/unstimulated ratio.
