Glucose Uptake Assay Kit (Fluorometric) ab136956 is a highly sensitive and easy to use non-radioactive kit which can detect glucose uptake as low as 50 pmol/well in a variety of cell types.
2-deoxyglucose (2-DG) is used in glucose uptake assay protocols because of its structural similarity to glucose. 2-DG is taken up by glucose transporters and metabolized to 2-DG-6-phosphate (2-DG6P). 2-DG6P cannot be further metabolized, and thus accumulates within cells. The accumulated 2-DG6P is directly proportional to 2-DG (or glucose) uptake by cells. In this assay, the accumulated 2-DG6P is enzymatically oxidized and coupled to a probe, which generates fluorescence in the presence of NADPH.
Glucose uptake assay protocol summary:
- prepare cells with suitable glucose starvation / uptake stimulation depending on experimental set-up
- add 2-DG to cells and incubate for 20 mins at 37ºC
- wash cells with PBS to remove exogenous 2-DG
- lyse cells with extraction buffer and repeated pipetting
- freeze/thaw lysates and optionally heat at 85ºC for 40 min
- cool on ice for 5 min
- add neutralizing buffer, spin and retain supernatant
- add supernatants and standards to wells
- add reaction mix and incubate for 40 min at 37ºC
If you want a more sensitive assay, we recommend using Glucose Uptake Assay Kit (Colorimetric) (ab136955), which contains an amplification step that allows the kit to detect < 10 pmol/well.

関連性Glucose (C6H12O6; FW: 180.16) is a ubiquitous energy source in most organisms, from bacteria to humans. The breakdown of carbohydrates produces mono- and disaccharides, most of which is glucose. Through glycolysis and TCA (citric acid cycle), glucose is oxidized to eventually form CO2 and water, generating the universal energy molecule ATP. Glucose is a primary source of energy for the brain and a critical component in the production of proteins and in lipid metabolism and therefore measurement of glucose level is a key diagnostic parameter for many metabolic disorders.
