Arginase I, also known as ARG1, is a 34.7kD protein expressed by neutrophils and myeloid-derived suppressor cells (MDSCs). There are two isoforms that are differentiated based on their tissue distribution and subcellular localization. Arginase I converts L-arginine into L-ornithine and urea; it is the final enzyme in the urea cycle. While mostly found in the liver, it can also be expressed in cells lacking a comprehensive urea cycle. Also, it contributes to vasodilation and vascular function. Arginase I is also reported to be involved in MDSC mediated suppression of T cell proliferation. Arginase I has been implicated in hyperargininemia (decreased function of arginase I) and Q fever.
Each lot of this antibody is quality control tested by intracellular immunofluorescent staining with flow cytometric analysis. For flow cytometric staining, the suggested use of this reagent is 5 µl per million cells in 100 µl staining volume or 5 µl per 100 µl of whole blood.
