Usage: This product is only for scientific research, and cannot be used for other purposes. (the following uses are for reference only) a coenzyme form of riboflavin, which plays a role in the dehydrogenation reaction catalyzed by flavin protein. FMN is suitable as a photopolymerization reagent in page, relying on the formation of free radicals (in the presence of light) in aqueous solution. There is no free radical formation in the presence of oxygen, but trace oxygen can re oxidize the nuclear yellow so that free radicals are produced. Catalysts TEMED or dmapn are often added to accelerate the formation of free radicals. Free radicals can cause acrylamide and bisacrylamide to polymerize to form gel, which is used to separate macromolecules. Because natural proteins are sensitive to the persulfate ion of ammonium persulfate, FMN is often used in non denatured page concentrate. Another advantage of FMN over ammonium persulfate is that it does not start polymerization until the glue is irradiated by light
