用途：5-FAM是一個純化的單一羧基異構體。它是最普遍的用來標記肽，蛋白質及核酸的綠色熒光試劑之一。它主要用來氬激光器488nm處被激發的一系列綠色熒光肽。同時也可用于配制各種小熒光分子。

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.

5-羧基熒光素是一種可用作酸堿指示劑的熒光染料，5-羧基熒光素具有極強的濃度依賴性并且可以顯示較強的熒光，可通過羧基和氨基的反應標記蛋白質，核甘酸和多肽。5-FAM
