5-Carboxyfluorescein diacetate, acetoxymethyl ester (CFDA, AM) is a cell-permeant esterase substrate that can serve as a viability probe that measures both enzymatic activity, which is required to activate its fluorescence, and cell-membrane integrity, which is required for intracellular retention of their fluorescent product.

It is widely recognized that fluorescent labeling of cells is an effective means to determine total cell numbers or how many viable cells exist in a sample.

5-CFDA-AM is a cell-permeable esterase substrate that can be used as an active probe to measure enzyme activity and cell membrane integrity. 5-CFDA-AM is electroneutral and can enter the cell at a lower concentration than CFDA, where it is hydrolysed by intracellular esterases to produce carboxyfluorescein. Carboxyfluorescein contains an additional negative charge and can be better retained in the cell[1].
