Cell viability at increasing concentrations of DMSO (0.1%, 0.25%, 0.5%, 1%, 2%, 4%, 16%, and 32%) in AGS (A), KATO III (B), and 293T (C) cell lines and at increasing concentrations of chloroform (0.1%, 1%, 5%, and 15%) in AGS (D), KATO III (E), and 293T (F) cell lines. The left side of each histogram shows the results from the resazurin assay, where viable cells reduce the reagent to a pink color, whereas nonviable cells retain the resazurin blue color. Ctrl: Cells in culture medium (control group). Statistical significance levels compared with the control group: *p < 0.05; **p < 0.01; **p < 0.001; ns not significant.
