Arginase Assay Kit is a quantitative colorimetric arginase determination.
ARGINASE (L-arginine ureohydrolase EC 18.104.22.168) is present in mammals and plants. In humans, arginase is expressed predominantly in the liver, and to lesser degrees in breast, kidney, testes, salivary glands, epidermis and erythrocytes. Arginase catalyzes the conversion of arginine to ornithine and urea, completing the last step in the urea cycle. Arginase activity is a key diagnostic indicator. Increased levels of arginase activity in blood have been associated with liver damage. Hyperargininemia due to arginase deficiency is an inherited autosomal recessive disease.
Direct Assays: arginase activity in enzyme preparations, serum, plasma, tissue culture etc;Drug Discovery/Pharmacology: effects of drugs on arginase activity.
