Abstract:

We developed a ratiometric fluorescent probe based on BODIPY which can detect GSH selectively. We did UV-Vis and fluorescence experiments and found that the UV-Vis and fluorescence spectra of probe 1 with GSH exhibited obvious red shifts. Probe 1 exhibited high selectivity and the detection inhibited the interference of Cys and was not interfered by other amino acids. The fluorescence titration experiments showed that probe 1 realized the quantitative detection of GSH with detection limit of 3.3×10-8 mol/L. The probe was successfully applied to the detection of GSH in living cells.

Key words: BODIPY, fluorescent probe, GSH
