    摘要： An object of the present invention is to provide a method for accurately evaluating the specific incorporation of D-glucose into cells. The present invention as a means for achieving the object is characterized by comprising contacting a D-glucose derivative that has a fluorescent chromophore in the molecule and is specifically incorporated into cells and an L-glucose derivative that has a fluorescent chromophore in the molecule with different cells in the same cell strain to be evaluated, respectively, comparing the fluorescence emitted by the D-glucose derivative that has a fluorescent chromophore in the molecule and is specifically incorporated into cells with the fluorescence emitted by the L-glucose derivative that has a fluorescent chromophore in the molecule, and evaluating the specific incorporation of D-glucose into cells relative to L-glucose by taking the difference between the two kinds of fluorescence intensities.
