ProteoGREEN™-gGlu is cancer-selective fluorescent imaging probe. This probe is rapidly activated by g-glutamyltranspeptidase (GGT), which is known to be tumor-associated enzyme, to give highly fluorescent compound.
The membrane-permeable ProteoGREEN™-gGlu is applicable to live cell or in vivo imaging of cancer cells.
ProteoGREEN™-gGlu has almost non-fluorescent in the absence of GGT. Treatment of ProteoGREEN™-gGlu with GGT results in a fluorescence turn-on with high S/N ratio.

Figure 1. The reaction mechanism of ProteoGREEN™-gGlu and GGT
Figure 2. The fluorescent spectra of ProteoGREEN™-gGlu after treated with GGT
ProteoGREEN™-gGlu was treated with GGT for 30 min at 37℃. After reacted, the fluorescence intensity markedly increased at 525 nm (S/N ratio).
