Fluorescein (FAM) is a popular fluorophore that has bright emission in the green area of visible spectrum. This derivative of fluorescein contains tetrazine moiety. Tetrazines react with trans-cycloalkenes and other strained olefins in a reaction called inverse electron demand Diels-Alder reaction (ied-DA). The reaction is very quick and specific. The reagent contains pure 6-isomer of FAM.
荧光素 (FAM) 是一种流行的荧光团，在可见光谱的绿色区域具有明亮的发射。 这种荧光素衍生物含有四嗪部分。 四嗪与反式环烯烃和其他应变烯烃在称为逆电子需求狄尔斯-阿尔德反应 (ied-DA) 的反应中发生反应。 反应非常迅速和特异。 该试剂含有纯的 FAM 6 异构体。
