Two novel chlorinated fluoresceins 4,7,2',7'-tetrachloro-6-(5-carboxypentyl)fluorescein (8a) and 4,7,4',5'-tetra-chloro-6-(5-carboxypentyl)fluorescein (8b) were synthesized as fluorescent probes for labeling proteins. These two fluoresceins contain 6-aminohexanoic acid as spacer linker to minimize the fluorescence quenching of the fluorescein molecules by the proteins to be labeled.
两种新型氯化荧光素4,7,2',7'-四氯-6-(5-羧基戊基)荧光素(8a)和4,7,4',5'-四氯-6-(5-羧基戊基)荧光素(8b)被合成为用于标记蛋白质的荧光探针。这两种荧光素包含6-氨基己酸作为间隔子接头,以最大程度地减少要标记的蛋白质对荧光素分子的荧光猝灭。
