Scientific Background
NpFR1, or napthalimide-flavin redox sensor 1, is a novel flavin molecule that exhibits a greater than 100-fold increase in fluorescence upon oxidation, and is easily reversible. In the oxidative form, is shows a maximum absorption at 395 and 463nm, max admission at 545nm. Treatment with a mild reducing agent (including sodium thiosulfate, sodium cyanoborohydride, DTT and glutathione) gave the reduced form which exhibited 110-fold lower absorbance, and 125-fold lower emission. Re-oxidation to its original fluorescence can be achieved by air or by hydrogen peroxide.
