APC anti-human Arginase I
Description
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.
Formulation
Phosphate-buffered solution, pH 7.2, containing 0.09% sodium azide and 0.2% (w/v) BSA (origin USA).Recommended Usage
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.
