Monitoring FSP1 activity with quinonecoumarin conjugates FAD, NADH and rhFSP1 in pH 7.4 TBS buffer were added in succession to varying concentrations of vitamin Kcoumarin or CoQcoumarin conjugate in pH 7.4 TBS buffer at 37 C (final concentration: 6 nM rhFSP1, 50 nM FAD, 200 M NADH) and the initial rates of the reaction were obtained by monitoring the increase in the fluorescence upon the reduction of the quinone to the hydroquinone on a plate reader ( ex / em = 415/470 nm)

One hypothesis for the mechanism of glucose toxicity is chronic oxidative stress (Robertson, 2004)
