Figure 1From: Gefitinib (IRESSA) sensitive lung cancer cell lines show phosphorylation of Akt without ligand stimulationIC50 values for 23 lung cancer cell lines using the MTT assay. Cell lines were classified as: sensitive (IC50≤1 μM), intermediate-sensitive (1 μM < IC50≤10 μM), and resistant (10 μM <IC50) to gefitinib. The bars represent the IC50 and standard deviation (SD) obtained in three indpendent MTT assays. Point: mean of three independent experiments, bar: ± SD.Back to article page
