TIRF images of HEK-β2AR-GFP cells on the fibronectin coated surface under ambient condition. The images were taken 2hrs after cell adhesion onto the fibronectin-coated biosensor surface in the absence and presence of an inhibitor. (a) no any inhibitor; (b) 10μM cytochalasin D; (c) 1mM RGD peptide. The inhibitors were present throughout the cell adhesion process. Image scale bar: 50 μm.
