荧光素二乙酸盐(FDA)是一种不发荧光的分子，在活细胞中水解产生发光荧光素。死细胞中无法积累或水解FDA。酯酶底物。FDA可透过细胞膜并作为荧光素积蓄在活细胞内。由于荧光素较BCECF或Calcein的亲水性低，因此荧光素从细胞中渗漏的量也高。FDA也可用于流式细胞仪。荧光素的激发和发射波长分别为488 nm和530 nm。荧光素二乙酸盐被用来区分活细胞和死细胞。 Fluorescein diacetate (FDA) is a non-fluorescent molecule, which is hydrolysed to fluorescent fluorescein in live cells. Dead cells cannot accumulate or hydrolyse FDA. Lipase substrate
