Arginase Activity Assay (Colorimetric) (ab180877) kit is a simple, sensitive and rapid assay to quantify arginase activity. Arginase reacts with arginine and undergoes a series of reactions that form an intermediate that react stoichiometrically with the probe to generate a colored product that can detected at OD = 570 nm.
The kit can detect less than 0.2 U/L Arginase activity in 96-well assay format.
Arginase (EC 18.104.22.168) is the final enzyme of the Urea Cycle. It converts L-arginine into urea and L-ornithine and plays an important role in removing ammonium ion from the body. Arginase has two isoforms: Arginase I and Arginase II. Arginase I is mainly present in the liver and plays an important part in the urea cycle whereas Arginase II is present in kidney and other tissues and regulates Arginine/Ornithine concentration. Arginase deficiency can lead to severe symptoms including neurological impairment, dementia and hyperammonemia. Analysis of Arginase activity is fundamental to the study of the urea metabolic pathway.
