Figure 3. Levels of vascular endothelial growth factor (VEGF) of malignant melanoma cells and ARPE-19 cells in the absence and presence of ranibizumab. Cell supernatants were assayed for enzyme-linked immunosorbent assay (ELISA) as described in the methods section. *p<0.05 compared to untreated cells. Data represents three independent experiment and all data points plotted as mean values±SD (*p<0.05).
