Fluorescence Spectra of ProteoGREEN™-gGlu after Treatment with GGT
ProteoGREEN™-gGlu was treated with GGT for 30 min at 37 °C. After activation the fluorescence intensity markedly increased at 525 nm (S/N>350).

Live Cell Imaging of Cancer and HUVEC Cells
Each cell type was treated with ProteoGREEN™-gGlu (2 µM) for 1 h. The reaction was completely inhibited by treatment with a GGT-selective inhibitor.

In Vivo Imaging

Features

  • Specific for cancer cells
  • High S/N ratio
  • GGT-activatable fluorescent probe
  • ProteoGREEN™-gGlu is almost non-fluorescent in the absence of GGT

Description

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