Expression of EGFR in Pancreatic Cancer Cell Lines. A, expression of EGFR was confirmed in S2VP10, S2CP9, MiaPaCa-2, PANC-1, and SKOV3.ip1 (EGFR positive control) cell lines; minimal expression was detected in NIH/3T3 (EGFR negative control) and MCF7 cells. B, dosimetry was performed using band intensity values for EGFR in comparison to actin. Values demonstrate the relative abundance of EGFR in each cell line.
