Ammonia is the primary central source of nitrogen for living systems. Ammonia is both a metabolic product and a necessary enzyme substrate for a wide range of reactions. It is created through nitrogen fixation or amino acid deamidation. It’s one of the primary contributors to acid/base balance. AkrivisBio’s Ammonia Assay provides a simple, sensitive procedure for the accurate determination of ammonia below 1 nmol per well. In the assay, Glutamate dehydrogenase converts NADH in the presence of ammonia plus α-ketoglutarate to NAD which is used to convert lactate to pyruvate. The pyruvate is oxidized forming hydrogen peroxide which is used by peroxidase to convert ADHP to resorufin with intense color (OD 570 nm).
