A cell-permeable, nonfluorescent, and hydrophobic compound, which is rapidly hydrolyzed by cytoplasmic esterases inside the cell, releasing the membrane-impermeable, hydrophilic, and intensely fluorescent calcein (excitation maximum: 494 nm; emission maximum: 517 nm). A cytosolic fluorophore that can also be used imaging mitochondrial permeability pore transition. Calcein is better retained by viable cells than fluorescein, carboxyfluorescein, and BCECF and its fluorescence is brighter in a variety of mammalian cell types. Useful for assessing adhesion, cell viability, chemotaxis and multidrug resistance (MDR).
