Uses

An uncharged, nonfluorescent molecule th at is useful for noninvasive bulk loading of cell suspension because it is capable of permeating the cell membrane. Cellular nonspecific esterases cleave its lipophilic blocking groups, resulting in a charged, fluorescent form of the molecule. Compared to the parent compound, this charged derivative leaks out of the cell at a much slower rate. Utilized for pH measurements in perfused tissues, intercellular spaces, mammalian cells, plant cells, bacteria, and yeast. Also, employed to investigate in assays for cellular functional properties such as adhesion, multi-drug resistance, viability and cytotoxicity, apoptosis and chemotaxis.', 'Cell-permeable ester of BCECF that, on hydrolysis by cytosolic esterases, yields the intracellularly trapped pH-indicator BCECF. Allows simultaneous recording of cell volume changes and intracellular pH in single osteosarcoma cells.
