Western blot analysis of pancreatic cell lines S2VP10L, MiaPaCa-2, S2013, and head and neck squamous cell carcinoma cell line SCC-1. a Western blot bands of β-Actin (42 kDa) and IGF1R (90 kDa). b Western blot band intensity dosimetry. The signal intensity of the IGF1R band was divided by the signal intensity of the β-Actin band to calculate relative abundance. Relative abundance of IGF1R in negative control SCC-1 cells was approximately 0.06. Pancreatic cell lines S2VP10L and S2013 displayed relative abundance of IGF1R of 0.32 and 0.42, respectively, a five- and seven-fold increase compared to the negative control
