Lidocaine does not affect cell viability of the Jurkat cell line. Jurkat cells were incubated for 24 h with graded concentrations of lidocaine or in media alone. Cell viability was assessed at the end of culture by an [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide] assay kit. The values represent the mean and standard deviation obtained in three different experiments. OD (a.u.): Optical density (arbitrary units). #P = not significant.
