ToxCount™ provides a two wavelength cell viability assay based on determination of live and dead cells. The assay uses fluorescent dyes that measure permeability of the plasma membrane of dying cells and the ability of living cells to retain intracellular esterases, respectively. Live cells are distinguished by the presence of ubiquitous intracellular esterase activity, determined by the enzymatic conversion of the non fluores…
