Storage

Supplied in 10 mM sodium HEPES (pH 7.5), 150 mM NaCl, 100 µg/ml BSA, 50% glycerol and less than 0.02% sodium azide. Store at –20°C. Do not aliquot the antibody.

Specificity / Sensitivity

Arginase-2 (D9J1N) Rabbit mAb recognizes endogenous levels of total arginase-2 protein. This antibody does not cross-react with arginase-1 protein.

Species Reactivity:

Human, Mouse, Rat

Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues near the carboxy terminus of human arginase-2 protein.

Background

Arginase-2 is a mitochondrial enzyme that catalyzes the hydrolysis of L-arginine to L-ornithine and urea (1). Research studies have shown that in acute myeloid leukemia (AML) patients, arginase-2 is released from AML blasts to the plasma, leading to the suppression of T-cell proliferation (2). It was also shown that arginase-2 is required for the immunosuppressive properties of neonatal CD71(+) erythroid cells, which inhibits neonatal host defense against infection (3). In addition, the expression of arginase-2 in dendritic cells is repressed by microRNA-155 during maturation (4). This repression is essential for T-cell activation and response (4).

Species Reactivity

Species reactivity is determined by testing in at least one approved application (e.g., western blot).

Western Blot Buffer

IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 5% w/v nonfat dry milk, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.
