  • Product overview

    Glucose Uptake Assay Kit (Colorimetric) (ab136955) is highly sensitive and easy to use non-radioactive kit which can detect glucose uptake as low as 10 pmol/well in a variety of cell types. Glucose uptake is an important biological process for studying cell signaling and glucose metabolism. Among many different methods available for measuring glucose uptake, 2-deoxyglucose (2-DG) has been widely used because of its structural similarity to glucose. As with glucose, 2-DG can be taken up by glucose transporters and metabolized to 2-DG-6-phosphate (2-DG6P). 2-DG6P, however, cannot be further metabolized, and thus accumulates in the 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, which can be determined by an enzymatic recycling amplification reaction.

  • Relevance
    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.

Customer reviews and Q&As

We would not recommend storing samples or stopping and storing samples during the assay procedure. However, if absolutely necessary the samples can be stored as cells at -80C before the addition of the extraction buffer to avoid any complications due t...

We have only tested this kit with human sample. However, we predict that this kit can work with a wide range of mammals including mouse.

Even though this kit has not been tested on bacterial samples, in principle it should work with samples from a wide range of mammals and bacteria. The method of detection is based on a biochemical reaction rather than an immunological reaction.

Thank you for your enquiry.

I can confirm that the 2DG in the kit can be dissolved in water and is soluble up to 100 mM in water.

I hope this will be helpful. If you have any further questions, please do not hesitate to contact me.

Serum starvation is required because serum can provide carbon source from which the cells can make glucose.

There should be no insulin in the media during starvation. After starvation, cells are stimulated with insulin to uptake glucose via t...

Glucose uptake assay of C. elegans

Excellent Excellent 5/5 (Ease of Use)
Abreviews
This kit worked well for C. elegans assay. We tried several 1) worm amount, 2) 2DG concentrations and uptake time, 3) sample dilutions. Here we provide the optimal protocol that we found in our trial.

1. Collect 50 ul of young adult worms for each sample in 1.5 mL tube (about 1/2 worms on 9 cm dish)
2. Resuspend worms in M9 buffer (or other saline for worm) and incubate for 1 hrs
3. Remove buffer and incubate worms in 0.5 mM 2DG in M9 buffer for 2 hr
4. Wash worms with ice-cold PBST for 3 times
5. Add 80 ul of Extraction buffer, pipette up and down, and freeze
6. Thaw samples at 85 C for 40 min
7. Add 10 ul Neutralization buffer and spin briefly
8. Dilute supernatant 1/8 times with Assay buffer
9. Add 10 ul Reaction mix A, incubate at 37 C for 1 hr
10. Add 90 ul Extraction buffer and heat at 85 C for 40 min
11. Add 12 ul Neutralization buffer
12. Transfer standards and samples to a 96 well plate
13. Add 38 ul Reaction mix B, pipette up and down
14. Measure absorbance at OD412 nm at 37 C every 5 min until 100pmol/well standard reaches OD412 nm = 1.5 - 2.0

To do the differentiation in the flask, the washing steps after differentiation will have to be done in tubes which can be spun down to collect cells. Then the starvation step has to be done again in a flask and the following washes in a tube, spinning...

The kit is based on the fact that DTNB is converted with enzyme to TNB which has absorption maxima at 412. As all the dyes have bell shaped curves so wavelengths higher or lower than maxima should also be suitable; individual absorption maxima curves c...

You need to increase the volumes of all reagents used such that the cells are covered and are not exposed to the air to dry out. For example, for the serum starvation, instead of using the 100 µl media for covering cells in the 96 well ...

I am happy to confirm that this kit can be used multiple times.

I recommend to store all the kit components at the recommended temps and in aliquots when possible.

Please take note that repeated freeze/thaw cycles will damage the co...
