a yellow dye that is visible even when highly diluted; used as an absorption indicator when silver nitrate solution is added to sodium chloride in order to precipitate silver chloride (turns pink when no chloride ions are left in solution and negative fluorescein ions are then absorbed)
Two cell types are each stained with a different fluorescent dye and then induced to fuse to form fusion products called heterokaryons. 两种细胞用不同的荧光染料分别进行染色,然后诱导融合产生被称为异核体的融合产物。
