Introduction
Ammonia is converted to urea in the urea cycle and excreted.
LabAssay™ Ammonia is the reagent kit for assay of ammonia based on a colorimetric method using the Berthelot reaction. This kit is used for the quantitative determination of ammonia in mouse and rat blood. It is a simultaneous multi-sample assay format using a microplate, but measurements can also be made using a test tube.
Assay principle
The Deproteinizing Reagent deactivates the enzymes and removes the components that inhibit color reaction in a sample. After adding Deproteinizing Reagent to a sample and centrifuging, add Phenol, Sodium Pentacyanonitrosylferrate(III) Dihydrate, and Sodium Hypochlorite to the supernatant. The indophenol blue pigment is obtained by the following schematic reaction. The amount of ammonia contained in the sample is determined by measuring the absorbance of the blue color.
