Product overview

Glucose Uptake Assay Kit (Colorimetric) (ab136955) is a highly sensitive and easy to use non-radioactive assay kit which can detect glucose uptake as low as 10 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 2-DG6P is oxidized to generate NADPH, the level of which can be determined by an enzymatic recycling amplification reaction.


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 heat at 85ºC for 40 min
– cool on ice for 5 min
– add neutralizing buffer, spin and transfer supernatant to new tubes
– add supernatants and standards to wells
– add reaction mix A and incubate for 1 hr at 37ºC
– add extraction buffer and heat to 90ºC for 40 min
– cool on ice for 5 min and add neutralizing buffer
– add reaction mix B
– analyze every 2-3 mins on microplate reader in kinetic mode at 37ºC

Notes

This product is manufactured by BioVision, an Abcam company and was previously called K676 Glucose Uptake Colorimetric Assay Kit. K676-100 is the same size as the 100 test size of ab136955.
