Treatment with platinum chemotherapeutics reduced cell viability in a concentration dependent manner. A549 (black line) and NCI-H358 (grey line) cells were treated with various concentrations of cisplatin (a), or carboplatin (b). Media and drugs were refreshed every 24 h for 72 h, then cell viability was measured with a WST-1 assay. All values are relative to the DMSO control and are presented as mean ± SEM (n = 3)
