Fluorescence imaging in living cells is typically carried out using a functionalized fluorescent dye. But it often causes strong background noise under many conditions where washing is not applicable. Here, we report on a coumarin based fluorogenic probe, which can be used as a bioorthogonal-labeling tool for glycoproteins. The results indicated that the probe was able to image glycoproteins in living cells and it may also be suitable for intracellular imaging.
