CheKine™ Lactate Dehydrogenase (LDH) Assay Kit

Product Information

  • Product name

    CheKine™ Lactate Dehydrogenase (LDH) Assay Kit

  • Application notes

    CheKine™ Lactate Dehydrogenase Assay Kit provides a simple and easy colorimetric assay for measuring Lactate Dehydrogenase in serum, plasma, cell culture supernatants, tissue/cell lysates culture medium, fermentation and other biological fluids. In this colorimetric assay, LDH reduces NAD to NADH, which then interacts with a probe to produce a color (λmax = 450 nm). The assay is quick and convenient.

Additional Information

  • Background

    Lactate dehydrogenase (LDH) is an oxidoreductase (EC presents in a wide variety of organisms. It catalyses the inter-conversion of pyruvate and lactate with concomitant inter-conversion of NADH and NAD+. It converts pyruvate, the final product of glycolysis, to lactate in hypoxic conditions. LDH quantification is of clinical interest as serum levels of certain LDH isozymes reflect pathological conditions in particular tissues. When disease or injury or toxic material damages tissues, the cells LDH is released into the bloodstream. Since LDH is a fairly stable enzyme, LDH has been widely used to evaluate the presence of damage and toxicity of tissue and cells.
