NBD-Fructose is a fluorescent derivative of fructose that is formed by coupling NBD-chloride with the amine group of amino fructose.1 It has been used to monitor fructose uptake by the GLUT5 transporter in MCF-7, MDA-MB-435, and MDA-MB-231 human breast cancer cells. NBD-Fructose displays excitation/emission maxima of 472/538 nm, respectively.
