Then, using hemin as catalyst, H2O2 produced by photochemical reaction oxidase p-hydroxyphenyl acetic acid ( HPA) and causes fluorescence reaction coupled of it. Based on this result, a new fluorimetric method was developed for indirect determination of glutaminic acid. 利用氯化血红素(hemin)作为过氧化酶的替代物,催化H2O2与对羟基苯乙酸(HPA)的偶合荧光反应,建立了间接荧光法测定谷氨酸的方法。
