Cat.No.:
Kit-2078
Product Overview:
The non-radioactive, colorimetric MDH assay is based on the reduction of the tetrazolium salt MTT in a NADH-coupled enzymatic reaction to a reduced form of MTT which exhibits an absorption maximum at 565 nm. The increase in absorbance at 565 nm is proportional to the enzyme activity.
Size:
100 tests
Description:
MALATE DEHYDROGENASE (MDH) (EC 1.1.1.37) is an enzyme which reversibly catalyzes the oxidation of L-malate to oxaloacetate in the presence of NAD. There are 2 isoforms in eukaryotic cells: MDH1 and MDH2. MDH1 found in the cytoplasm and plays a key part in the malateaspartate shuttle for transporting malate into the mitochondria. MDH2 is a mitochondrial enzyme which participates in the TCA cycle that reversibly converts L-malate into oxaloacetate. Higher MDH activities are found in some neurodegenerative diseases such as Alzheimer"s disease.
Applications:
For quantitative determination of L-malate dehydrogenase enzyme activity and drug effects on malate dehydrogenase metabolism.
Storage:
The kit is shipped on ice. Store all components at -20°C upon receiving. Shelf life: 6 months after receipt.
