2-NBDG is a fluorescent derivative of glucose whose uptake is competitively inhibited by D-glucose , but not L-glucose or sucrose, in E. coli. It has been used to monitor glucose uptake by bacteria and live mammalian cells and in tumor biopsies. 2-NBDG displays excitation/emission maxima of 475/550 nm, respectively.
2-NBDG is a fluorescent glucose uptake indicator, used in real-time confocal, high-resolution, or wide-field fluorescence microscopy as well as in flow cytometry.
