描述
应用 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。
产品介绍 Fluorescein diacetate stains living cells green, and is a substrate for esterases. Fluorescein Diacetate is suitable for use in cell viability assays. Removal of the acetate groups by cellular esterases results in fluorescence in cells with intact membranes.
