Cytotoxicity of free KLA peptide, poly[(KLAAm10-co-DMA30)-b-(DAAm280-co-DMA120)] (NP3), and poly[(KLAAm10-co-DMA10)-b-(DAAm280-co-DMA120)] (NP5) using a CellTiter-Blue cell viability assay. Concentrations were calculated with respect to the total KLA peptide content. HeLa cells were treated with peptide-containing materials and incubated for 72 h at 37 °C. Data displayed as mean ± standard deviation of three independent experiments.
