Photobleaching test to compare photostability of Her-HMIGeR and Her-CypHer. NIH3T3/HER2( + ) cells were incubated with 150 nM Her-HMIGeR or Her-CypHer for 24 h, and bright-field and fluorescence images were captured. Then, the cells were exposed to excitation light (with the same power for observation of fluorescence) for 1 min, and fluorescence images were obtained again. Excitation and detection wavelengths were 670 nm and 690–800 nm for Her-HMIGeR, and 650 nm and 670–800 nm for Her-CypHer. Scale bars represent 50 μm
