Summary
The measurement of cell injury or cytotoxicity produced by chemicals or toxicants in cell culture has routinely been evaluated by such criteria as plating efficiency, cell growth, protein or DNA synthesis, and cell viability. We describe a more sensitive and earlier index of cytotoxicity: leakage of cytoplasmic enzymes from injured cells into the culture medium.
