Ammonia Assay Kits

Ammonia assay kits are available to determine the amount of ammonia present in a sample. Ammonia is an important nitrogen source and metabolic product that is involved in many biological pathways. In measuring ammonia concentrations, some assays use an enzyme-based reaction, in which the reaction of ammonia with glutamate dehydrogenase is coupled to the oxidation of NADPH. This causes a reduction in absorbance at 340 nm that is directly proportional to the concentration of ammonia in the sample. Other assays may use an o-phthalaldehyde-based reaction that produces fluorescence proportional to the concentration of ammonia. Ammonia assay kits can be used in studying ammonia imbalances relating to various diseases and ammonia-based metabolic activities.
