Description
Fluorescein diacetate stains living cells green, and is a substrate for esterases. It is suitable for use in cell viability assays. Removal of the acetate groups by cellular esterases results in fluorescence in cells with intact membranes. It is used in studies on intracellular interactions and membrane permeability.Related product price
