Rediject 2-DG on the ASK



Tumor cells exhibit a different metabolic pattern than normal cells, which includes an increase in glucose uptake (their main source of generating energy). Therefore, cancer cells exhibit an elevated glucose metabolism and up-regulation of glucose transporters (GLUTs) compared to non-tumor cells. XenoLight RediJect 2-DeoxyGlucosone (DG) 750 is a fluorescent probe for in vivo targeting of tumors which exhibit an elevated glucose uptake rate in comparison to surrounding tissues. To achieve maximum glucose targeting and enhanced tumor uptake, the probe has been designed to contain four 2-DG molecules per dye molecule.

Figure 1: Female C57 BL/6 albino mice were subcutaneously injected with 1 million LL2-luc cells. At 2-3 weeks, tumors were about 100-200 mm3. Mice were intravenously injected with 2-DG750 probe (10 nmol/mouse) and imaged with IVIS Spectrum at indicated time points using 745 nm excitation and 800 nm emission filter set. Quantification of the signal from tumor and control background area was plotted on the middle panel graph. Signal to background ratio was shown on the right panel.

As indicated above, RediJect 2-DG 750 probe showed specific accumulation to LL-2 tumors shortly after delivery. In addition, specific tumor labeling with the RediJect 2-DG 750 probe has also been demonstrated with Prostate (PC-3M) and Lung (NCI-H460) tumors, further validating the utility of this probe as a generic fluorescence reagent for in vivo tumor targeting.

Application notes and posters

  • Poster: Multivalent Fluorescent Probes for In Vivo Tumor Targeting


RediJect 2-DG control dye (Cat. No. 760567) is a non-reactive dye that can be used as a negative control when using the RediJect 2-DG-750 fluorescent imaging probe. This dye controls for passive dye accumulation, as any retention of probe that is not due to actual metabolism-related glucose uptake will also be observed with the control dye.
