詳細

General description

A cell-permeable, non-fluorescent, and hydrophobic compound, which is rapidly hydrolyzed by intracellular esterases releasing the membrane-impermeable, hydrophilic, and intensely fluorescent calcein. Can also be used for imaging mitochondrial permeability pore transition. Calcein is better retained by viable cells than fluorescein, carboxyfluorescein, or BCECF, and its fluorescence is brighter in a variety of mammalian cell types. Useful for assessing adhesion, cell viability, chemotaxis, and multidrug resistance (MDR).

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).
