EGFR and neoplasm: To confirm co-localization of Fl-Q-ASO and EGFR mRNA in tumor cells and to assess cell morphology, phase-contrast/fluorescence images were collected at various excitation wavelengths (blue fluorescence mode, λex = is 358 nm, green fluorescence mode, λex = 458/500 nm; red fluorescence mode, λex = 587 nm) (Figure 9D).
