Imaging of endogenous ONOO⁻ in RAW 264.7 cells. (a) Cells were preincubated with HND-ONOO. The cells were stimulated with LPS/INF-γ and then incubated with HND-ONOO. The cells were stimulated with LPS/INF-γ and treated with (c) Tempol, (d) AG, and (e) uric acid and then stained by HND-ONOO. The scale bar is 20 μm.
