From: Application of impedance measurement to investigate in vitro inhalation toxicity of bacteria
ECIS real-time monitoring of NuLi-1 cells in the presence of bacterial toxins. Streptolysin O (a), Nigericin (b) and Hygromycin (c) were applied at different concentrations to NuLi-1 cells and their effects on the impedance were measured over 48 h. Averages of normalized impedance differences between toxin exposed data and control data are shown from triplicates. Cell culture medium treated cells were used as controls. Impedance was normalized to cell values at the time of toxin addition
