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

【Principle】

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.

【Samples】

serum, plasma, cell culture supernatants, tissue/cell lysates, culture medium, fermentation and other biological fluids.

【Kit components】

Name Storage temperature Function
Assay Buffer 4ºC maintain reaction environment
Lactate -20ºC LDH substrate
NAD -20ºC LDH substrate
WST-8 -20ºC, protect from light coloration
Enhancer -20ºC, protect from light electron transport complex
LDH Standard -20ºC Prepare standard curve

【Procedure】

  1. Working Reagent Preparation
  2. Add standard and sample per well, then add Working Reagent to each well. Tap plate to mix. Immediately read optical density at 450nm (OD0).
  3. Incubate for 30 min at 37°C in the dark. Read optical density at 450nm again (OD30).
