生物活性
5-FAM SE is a single isomer, is a fluorescent labeling reagent used for labeling peptides, proteins and nucleotides. 5-FAM SE can react with amines and can yield stable amine conjugates[1][2].
体外研究 (In Vitro)
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[1]. 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)[2].
MCE has not independently confirmed the accuracy of these methods. They are for reference only.

5-FAM (5-Carboxyfluorescein) is a green fluorescent reagent used for in situ labeling peptides, proteins and nucleotides. 5-FAM is a single isomer with Ex/Em of 490 nm/520 nm[1].
体外研究 (In Vitro)
5-FAM contains a carboxylic acid that can be used to react with primary amines via carbodiimide activation of the carboxylic acid. Fluorescein is the most common fluorescent derivatization reagent for labeling biomolecules. In addition to its relatively high absorptivity, excellent fluorescence quantum yield, and good water solubility, fluorescein has an excitation maximum that closely matches the 488 nm spectral line of the argon-ion laser[1].
