Binding of chloroplast-made (HE)3-DARPin G3 to HER2 on different cell lines by immunofluorescent microscopy. Cells were incubated with chloroplast-made DARPin G3 followed by a FITC conjugated antibody which showed the HER2 specific targeting on the cell surface. Laser power and gain were kept constant, and brightness and contrast settings were adjusted equally. The scale bar represents 20 μm
