Expression of EGFR, α 2 /β 1 integrin in Capan-1 cells. Cells were cultured on Transwell inserts, and confocal immunofluorescence microscopy performed following incubation with primary antibodies against EGF-R (A), α2 integrin (B) and β1 integrin (C). Negative controls with primary antibody omitted did not show a detectable signal.
