Figure 1. Iopromide inhibits HEK 293 cell proliferation. HEK 293 cells were seeded in 96 well plates for 24 h and subsequently incubated with 0, 25, 50, 100, and 200 mgI/ml iopromide for either 24 h (A) or 48 h (B). Cell viability of HEK 293 cells was evaluated using the MTT assay. The results are expressed relative to those of the untreated control and values are presented as mean±SE (n=3) (***p<0.001).
