2-NBDG，10MG，SML4177-10MG，Sigma

Application

2-Deoxy-2-[(7-nitro-2,1,3-benzoxadiazol-4-yl)-amino]-D-glucose (2-NBDG) may be used as a surrogate reagent to visualize glucose uptake in live cells and tissues for metabolic studies.

Biochem/physiol Actions

2-NBDG, a fluorescent 2-deoxyglucose analog (excitation/emission: ~470/545 nm), supplied as a mixture of α-and β-anomers, enters cells via GLUT transporters, competing with D-glucose. Intracellularly, hexokinase phosphorylates 2-NBDG at C-6, mimicking the first step of glycolysis, before it degrades to a non-fluorescent derivative. This sensitive fluorescent non-toxic tracer illuminates glucose uptake in diverse cell types (e.g., adipocytes, myocytes, tumor cells), offering insights into glycolytic flux, mitochondrial activity, and overall cellular energetics. Compatible with confocal microscopy, flow cytometry, and spectrofluorometry, 2-NBDG (typically used at 10 μM, 37°C, 60 min) enables real-time monitoring of glucose transport kinetics and metabolic dynamics in various biological systems, from insulin-responsive tissues to cancer models.
