Viability of U2transLUC cells using crystal violet assay or by monitoring the GFP-intensity per well. U2transLUC cells were exposed to 0.05%, 0.10%, 0.25%, 0.50% or 1% sodium azide for three hours and processed as described in the "Methods" section. The values are the means (± SD) of GFP intensity per well or the absorbance at 595 nm from three independent experiments.
