In vitro cell viability and Osimertinib IC50 assay. (a) Cell viability of PC9 and PC9-GR cell lines treated with Gefitinib. (b) PC9 and PC9-GR were incubated with Gefitinib at different concentrations for 72 hours. MTT was used to detect the inhibitory effect of Gefitinib on cell proliferation. (c) The cell viability of PC9 and PC9-GR cell lines treated with Osimertinib. (d) PC9 and PC9-GR were incubated with different concentrations of Osimertinib for 72 hours. MTT was used to detect the inhibitory effect of Osimertinib on cell proliferation. (e) The cell viability of H1975 and H1975-OR cell lines treated with Osimertinib. (f) H1975 and H1975-OR were incubated with different concentrations of Osimertinib for 72 hours. MTT was used to detect the inhibitory effect of Osimertinib on cell proliferation.
