Figure 8: GSH probe prototypes.
(a) Chemical structures of TQG-CN and TQG-CN-GSH and its confocal images in HeLa cells. (b) Chemical structures of RT-NH2 and RT-NH2-GSH and its confocal images in HeLa cells. Scale bar 10 μm. It should be noted that neither TQG-CN nor RT-NH2 distributes in the nucleus, which is a hallmark of protein binding for fluorescent probes.
