NAD/NADH Assay Kits

NAD/NADH assay kits are available from several suppliers to measure the amount of the metabolic cofactor nicotinamide adenine dinucleotide (NAD). NAD, which exists in oxidized (NAD+) and reduced (NADH) forms, acts as an important electron acceptor in cellular processes, such as the electron transport chain for ATP generation. NAD+ and NADH are also used as enzyme substrates for protein posttranslational modifications. NAD/NADH assay kits use a cyclic enzymatic reaction in which NAD+ is reduced to NADH, which reacts to form a colored product. The intensity of the color is proportional to the amount of NAD+ and NADH in a sample. NAD/NADH assays are used in assessing cellular metabolic activities.
