The Pierce LDH Cytotoxicity Assay Kit measures extracellular LDH in culture media using an enzymatic reaction that results in a red formazan product which can be measured spectrophotometrically. Lactate dehydrogenase (LDH) is a cytosolic enzyme that is is an indicator of cellular toxicity. The assay is ideal for high-throughput screening and provides a safe alternative to radioactive cytotoxicity assays.


  • Convenient – add–mix–read assay format for adherent and suspension cells

  • Colorimetric – quantitatively measures LDH release by formation of colored product

  • Robust – uses stable LDH enzyme activity as a cytotoxic marker

  • Flexible – ideal for high–throughput screening

  • Non–radioactive – safe alternative to 51Cr–release cytotoxicity assays


Kit contains substrate mix, assay buffer, 10X lysis buffer, stop solution, and LDH positive control


Microplate reader capable of reading absorbance at 490nm and 680nm, flat-bottom clear 96–well plate compatible with spectrophotometer, multichannel pipette

Recommended for:

  • Measure in vitro cytotoxicity mediated by chemicals, immune cells, or siRNA or microRNA
  • Detect cytolysis in bioreactor or 3D tissue engineering applications
