用途：5-FAM是一个纯化的单一羧基异构体。它是最普遍的用来标记肽，蛋白质及核酸的绿色荧光试剂之一。它主要用来氩激光器488nm处被激发的一系列绿色荧光肽。同时也可用于配制各种小荧光分子。

5-FAM is the purified single isomer of carboxyfluorescein. It is one of the most popular green fluorescent reagents used for labeling peptides, proteins and nucleotides. It has been predominantly used to develop a variety of green fluorescent peptides that can be excited with the 488 nm line of the Ar laser. It has also been used to prepare various small fluorescent molecules.
