Fig. 1From: Application of impedance measurement to investigate in vitro inhalation toxicity of bacteriaViability of NuLi-1 cells exposed to bacterial toxins. Streptolysin O (circles), Nigericin (rectangles) and Hygromycin (squares) were applied in different concentrations to NuLi-1 cells and the viability was measured at 24 (filled symbols) and 48 h (empty symbols) using the PrestoBlue™ assay. Results are shown as a percentage of viable cellsBack to article page
