Quantitative determination of LDH in samples, Abbkine CheKine™ Lactate Dehydrogenase (LDH) Assay Kit will offer you an easier method

Lactate dehydrogenase (LDH) is an oxidoreductase found in nearly all living cells (animals, plants, and prokaryotes). LDH catalyzes the conversion of lactate to pyruvate and back, as it converts NAD+ to NADH and back. A dehydrogenase is an enzyme that transfers a hydride from one molecule to another.

Quantification of Lactate dehydrogenase has clinical significance because serum levels of certain lactate dehydrogenase isoenzymes reflect the pathological conditions of specific tissues. When tissue is damaged by disease, injury, or toxic substances, lactate dehydrogenase is released into the bloodstream. Because lactate dehydrogenase is a fairly stable enzyme, it has been widely used to evaluate tissue, cell damage and toxicity.

Abbkine CheKine™ Lactate Dehydrogenase (LDH) Assay Kit, more simple, convenient and sensitive

Product Name CAT #
CheKine™ Lactate Dehydrogenase Assay Kit KTB1110


provides a simple and easy colorimetric assay for measuring LDH in samples. In this colorimetric assay, LDH reduces NAD to NADH, which then interacts with a probe to produce a color (λmax = 450 nm), the LDH present in the sample is proportional to the signal obtained.
