Effect of PC9 and PC9-GR cells on the hydrogel based peptide array. (A) Detection of acquired resistance by the peptide array upon incubation of the immobilized substrate with PC9 and PC9-GR cells in the presence of gefitinib. (B) Comparison of the effect of gefitinib and CL-387,785 on substrate phosphorylation when incubated with PC9-GR cells. Each data point represents the mean of three independent experiments in which each experiment contained three replicates. The error bars represent s.e.m. (n=3).
