Detection Principle Malate dehydrogenase widely exists in animals, plants, bacteria and other organisms, is one of the key enzymes in tricarboxylic acid cycle, catalyze between malic acid and oxaloacetic acid reversible conversion. MDH can be divided into NAD-dependent MDH and NADP-dependent MDH according to different coenzyme specificity. NAD-MDH usually exists in the cytoplasm and mitochondria of bacteria and eukaryotic cells.
NAD-MDH catalyzes the conversion of substrate malic acid and NAD to oxaloacetic acid and NADH. NADH makes WST-8 orange under the action of electron coupling agent. The activity of NAD-MDH can be calculated by measuring the change of absorbance value at 450 nm.
