Product overview
LDH Assay Kit (Cytotoxicity, Fluorometric) (ab197004) provides a sensitive, quick, and easy way to detect LDH (lactate dehydrogenase) released from damaged cells.
In the LDH 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. 5µl of cell culture media required per assay.

Notes
Alternative LDH assays
If you would like to use a fluorometric assay, please refer to LDH-Cytotoxicity Assay Kit (Fluorometric) (ab197004).
This kit is more sensitive than the colorimetric LDH Cytoxicity Assay Kit ab65391.
To measure LDH activity in sample types such as serum, plasma, and cell lysates, we recommend LDH assay kit ab102526.
