Effects of the silver materials on A549 cell viability and their cytotoxic potential. A. Cell viability of naïve cells (left panel) and cells stimulated with 20 ng/ml rh-TNF-α (right panel) was assessed after 48 h incubation using the CellTiter-Blue® assay from Promega. Data are presented as mean ± stdev of at least 6 independent wells. B. Cytotoxicity of the different silver preparations was tested after a 48 h incubation using the CytoTox 96® Non-Radioactive Cytotoxicity Assay Kit from Promega. Data are presented as mean ± stdev of 6 independent wells.
