The capillary electrophoresis (CE)-laser-induced fluorescent (LIF) method with 5-FAM SE (5-Carboxyfluorescein N-succinimidyl ester) derivatization for the analysis of serotonin can be used to quantify luminally released 5-HT with high sensitivity. CFSE is an excellent dye for the derivatization of 5-HT. 5-FAM SE (5-Carboxyfluorescein succinimidyl ester) is chosen as the labeling reagent to precapillary derivatize the two marker aminohydroxyphenylalanine (AHP) isomers produced after reductive hydrolysis of pheomelanin with hydriodic acid (HI).
生物活性
5-FAM SE 是一种单一异构体,是一种用于标记肽,蛋白质和核苷酸的荧光标记试剂。5-FAM SE 可以与胺反应,并可以产生稳定的胺结合物。
