Supplementary Figure 4: Representative images of MG-2I−induced cytotoxicity on HEK cells expressing FAP in the transmembrane, mitochondria, nucleus and cytosol, and of KillerRed−induced cytotoxicity targeting mitochondria.
From: A genetically targetable near-infrared photosensitizer

FAP expressing cells were mixed with wild type HEK cells and then incubated with 400 nM of MG-2I (Each condition was repeated at least 4 times). Images were taken at the same conditions as for illumination (c560 of KillerRed was taken at 30% laser power to avoid saturation, 100% laser power used for illumination). Illumination conditions are denoted on the images in the ‘after illumination’ column, cell viability was determined with Live/Dead cell fluorescent assay 3 hour post illumination. (Scale bar = 10 μm)
