Effect of Surfactants on the Viability of Polarized and Confluent MDCK Cells as Evaluated by the LDH Leakage Assay.

Cell viability is expressed relative to the viability of mock-exposed cells. Each value results from at least 3 independent experiments, in which each surfactant concentration was examined at least in triplicate. Data are shown as mean±SD (n = 3). ***, p<0.001. In the case of SDS a significant lifting-off of the MDCK cells was observed at higher surfactant concentrations. In these samples the results of the LDH leakage test were considered to be not reliable and the values were, therefore, not determined (n.d.).
