Cell death or cytotoxicity is classically evaluated by the quantification of plasma membrane damage. Lactate dehydragenase (LDH) is a stable enzyme, present in all cell types, and rapidly released into the cell culture medium upon damage of the plasma membrane. LDH activity, therefore, can be used as an indicator of cell membrane integrity and serves as a general means to assess cytotoxicity resulting from chemical compounds or environmental toxic factors. BioPioneer’s LDH Cytotoxicity Assay Kit measures LDH activity present in the culture medium using a coupled two-step reaction. In the first step, LDH catalyzes the reduction of NAD+ to NADH and H+ by oxidation of lactate to pyruvate. In the second step of the reaction, WST-1 uses the newly-formed NADH and H+ to catalyze the reduction of a tetrazolium salt to highly-colored formazan which absorbs strongly at 450-490 nm.
