Evaluation of the toxicity of SART in vitro in cultured cells. The cell line A20 (3  × 104 cells/well) was cultured in the presence of the indicated concentrations of SART. Control cultures were established without the addition of SART. Cultures were incubated for 48 h at 37°C in a 7% CO2 atmosphere. Cell viability was measured by the XTT reduction measurement. Ctr viable indicates untreated cultures incubated with medium alone. Ctr dead indicates control cultures to which 1 μL of Triton X-100 was added prior to the addition of XTT. Mean values ± SD of absorbance (A450) are shown.
