Figure 1

Surface expression of IGF-1R and EGFR in human breast cancer cell lines. Untreated cells were stained with phycoerythrin-conjugated anti-IGF-1R (insulin like growth factor-1 receptor) or with fluorescein-isothiocyanate-conjugated anti-EGFR (anti-epidermal growth factor receptor) antibody. Shaded peaks show flow cytometry analysis of the number of insulin-like growth factor 1 (top row) and epidermal growth factor (bottom row) receptors on the surface of MDA468, MCF-7, MDA231, and SK-BR-3 human breast cancer cells. Outlined peak represents isotype control (normal mouse IgG1). Counts indicate number of events.
