Insulin-like growth factor-I receptor in proliferation and motility of pancreatic cancer

Figure 1 Western blotting analysis of pancreatic cell lines. Protein was isolated from cultured pancreatic cancer cell lines in 100 mL/L fetal bovine serum (FBS), and subjected to western blot analysis. It was shown clearly that all cell lines expressed IGF-IR as well as phosphorylated IGF-IR (pIGF-IR). Tubulin-α was used as an internal control. 1: MIA-Paca2; 2: NOR-P1; 3: PANC-1; 4: PK-45H; 5: PK-1; 6: PK-59; 7: KP-4.
