CellCountEZ™ Cell Survival Assay Kit is a tissue culture media-based assay that can measure metabolically active live cells and quantify cell death caused by radiation, chemotherapeutics or toxins. CellCountEZ™ is based on the ability of mammalian cells to rapidly and efficiently convert hydroxyethyl disulfide (HEDS) into mercaptoethanol (ME) through a bioreduction mechanism. Bioconversion of HEDS to ME relies on the activity of the oxidative pentose phosphate cycle (OPPC). CellCountEZ™ measures ME in the extracellular medium without the need for cellular lysis and extraction methods, this preserves the ability to perform other cellular tests in the same culture system. CellCountEZ™ is readily soluble, membrane permeable and converted by live cells intracellularly before transport into the extracellular culture media. CellCountEZ™ offers many advantages that make it superior to common existing methods for quantifying cell growth and survival.
