To determine 2-deoxy-D-glucose (2DG) and 2-deoxy-D-glucose 6-phosphate (DG6P) in mouse tissue after injection of 2DG, we have developed a novel assay. This assay is a simple procedure involving incubation of samples with four independent, single reaction mixtures followed by measurement of fluorescence. From differences between the values obtained with the four reactions, each of glucose, glucose 6-phosphate, 2DG and DG6P were able to be quantified in a sensitive manner. Using this assay system, glucose and 2DG in blood and DG6P-accumulation in muscle were easily determined. Therefore, this assay may be useful for measuring in vivo glucose uptake without the use of radioisotopes. (c) 2008 Elsevier Inc. All rights reserved.
