Product overview
LDH-Cytotoxicity Assay Kit (Fluorometric) (ab197004) provides a sensitive, quick, and easy way to detect LDH (lactate dehydrogenase) released from damaged cells. In this assay, LDH converts lactate to pyruvate and NADH, which reduces a proprietary probe to an intensely fluorescent product (Ex/Em = 535/587 nm). The amount of fluorescence is directly proportional to the number of damaged cells. The assay is adaptable to high-throughput format and can be completed in less than 20 min. Sensitivity: ~ 100 cells.

Notes
Cell death or cytotoxicity is classically evaluated by the quantification of plasma membrane damage. Lactate dehydragenase (LDH, EC 1.1.1.27) is a stable enzyme, present in all cell types, which is rapidly released into the cell culture medium upon damage of the plasma membrane. LDH, therefore, is the most widely used marker in cytotoxicity study.
