製品の概要
Ammonia Assay Kit (ab83360) provides a rapid, simple, sensitive, and reliable assay for ammonia and ammonium.
In the ammonia assay protocol, ammonia and ammonium are converted to a product that reacts with a probe to generate color (λmax = 570 nm) which can be easily quantified by plate reader. The kit can detect 1 nmol (~20 µM) of total ammonia and ammonium, which is much more sensitive than measuring ammonia with a NADPH based assay.
Ammonia assay protocol summary:
- add samples and standards to wells
- add reaction mix and incubate for 60 min at 37ºC
- analyze with microplate reader -
特記事項
This product is manufactured by BioVision, an Abcam company and was previously called K370 Ammonia Colorimetric Assay Kit. K370-100 is the same size as the 100 test size of ab83360.
Ammonia assays measure the total level of the ammonium ion and of ammonia in a sample.
At a physiological pH, nearly all ammonia exists as ammonium in solution.
The chemical equation that drives the relationship between ammonia and ammonium is: NH3 + H2O ↔ NH4+ + OH-
When the pH is low, the reaction is driven to the right, and when the pH is high, the reaction is driven to the left. In general, at around room temperature, at a pH less than 6.0, the proportion of ammonium-N plus ammonia-N as NH3 is very low and as NH4+ is very high. At a pH around 8.0 (the ammonia assay buffer pH), the proportion as NH3 is 10 percent or less.
This is our most popular ammonia assay kit; ammonia assay kit ab102509 uses an alternative non-enzymatic method.

Ammonia is an important source of nitrogen for living systems. Nitrogen is required for the synthesis of amino acids, which are the building blocks of protein. Ammonia is a metabolic product which is created through amino acid deamination. It plays an important role in both normal and abnormal animal physiology like normal animal acid/base balance.

Zhiyuan Li et al. used ammonia assay kit ab83360 to examine the build-up of ammonia in old cell culture medium containing glutamine and how this might induce autophagy in cultured cells.
The ammonia assay was used to measure the ammonia concentration in cell culture medium containing Glutamine (medium alone, without cells) which was stored at 4°C or at 37°C for between 1-7 days. They found that ammonia levels increased significantly in the medium stored at 37°C.

Kyle Wilson et al. used ammonia assay kit ab83360 to examine ammonia levels in liver tissue in response to P. chabaudi infection. They found that in IL-10 KO mice, ammonia levels were not elevated above WT during P. chabaudi infection.
WT and IL-10 KO mice were infected with P. chabaudi and monitored during the peak of infection. WT mice were sacrificed at the peak of infection (day 10 p.i.) and IL-10 KO mice upon severe morbidity as determined via SHIRPA score.
