Description
Glucose Uptake Assay Kit (Fluorometric) (BA0102) (BA0102)
The Glucose Uptake Assay Kit (Fluorometric) (SKU: BA0102) is a fluorescent, cell-based assay for measuring glucose uptake in whole cells. It uses 2-deoxyglucose (2-DG), a glucose analogue taken up by glucose transporters and phosphorylated by hexokinase to 2-deoxyglucose 6-phosphate (2-DG6P), which accumulates intracellularly. After lysis, excess NADP and glucose 6-phosphate dehydrogenase metabolise 2-DG6P to generate NADPH, which is measured through a recycling reaction that amplifies the signal. The resulting fluorescence at 530/585 nm is proportional to the 2-DG6P concentration. The kit is non-radioactive and can be automated as a medium-throughput assay.

Note: The below protocol is a sample protocol. Protocols are specific to each batch/lot. For the correct instructions please follow the protocol included in your kit.
| Step | Procedure |
| 1 | Culture, starve and treat cells: seed cells into a 96-well culture plate and incubate. Incubate with low-glucose, low-serum media to raise glucose demand, wash twice with 37C PBS, then starve in glucose-free, serum-free media for 40 minutes, adding any treatments at this step. |
| 2 | Add 2-deoxyglucose: add 10 uL of 2-DG substrate per well and incubate for 20 minutes. Remove media and wash three times with ice-cold PBS. |
| 3 | Lyse and extract 2-DG6P: add Lysis Buffer (1% Triton X-100 in NADP Extraction Buffer), shake, then heat at 80C for 10 minutes. Prepare the 2-DG6P standard curve, add NADPH Extraction Buffer, cool the plate, then add Working Reagent 1 (Assay Buffer, Enzyme A, NADP) and incubate at 37C for 60 minutes. |
| 4 | Extract and measure NADPH: add NADPH Extraction Buffer and heat, add NADP Extraction Buffer and cool, then transfer 50 uL of each sample and standard to a black 96-well plate. Prepare Working Reagent 2 with diluted Enzyme A, Enzyme B, G6P Reagent and Probe. |
| 5 | Add 50 uL Working Reagent 2 per well and read at 530/585 nm over 20 minutes, recording fluorescence at time zero (F0) and at 20 minutes (F20). |
Compute delta-F for each standard and sample by subtracting F0 from F20. Plot the standard delta-F values and determine the slope. [2-DG6P] = (delta-F_Sample - delta-F_Blank) / Slope x n, where delta-F_Blank is the value of the water standard and n is the dilution factor.
