Figure 2From: Silencing the epidermal growth factor receptor gene with RNAi may be developed as a potential therapy for non small cell lung cancerThe effects of dsRNA-EGFR on A549 (A) and SPC-A1 (B) cell count and colony formation (C). Cells were seeded into 6 well plates at a density of 1 × 105 per well. Forty-eight hours after transfection, cell numbers were determined using a hemocytometer. For colony forming assay, cells transfected with siRNA,Back to article page
