Species cross-reactivity is determined by western blot.
Applications Key: W=Western Blotting, IHC-P=Immunohistochemistry (Paraffin), IF-F=Immunofluorescence (Frozen), IF-IC=Immunofluorescence (Immunocytochemistry),
Specificity / Sensitivity
Arginase-1 (D4E3M™) XP® Rabbit mAb recognizes endogenous levels of total arginase-1 protein. This antibody does not cross-react with arginase-2.
Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Val47 of human arginase-1 protein.

Confocal immunofluorescent analysis of mouse liver (positive; left) or small intestine (negative; right) using Arginase-1 (D4E3M™) XP® Rabbit mAb (green). Blue pseudocolor = DRAQ5 #4084 (fluorescent DNA dye).
Confocal immunofluorescent analysis of mouse primary bone marrow-derived macrophages (BMDMs) using Arginase-1 (D4E3M™) XP® Rabbit mAb (green). BMDMs were differentiated with M-CSF (20 ng/ml, 7 days) and activated with either IL-4/cAMP (20 ng/ml, 0.5 mM, 24 hours; left) or LPS/IFNγ (50 ng/ml, 20 ng/ml, 24 hours; right). Red = Propidium Iodide (PI)/RNase Staining Solution #4087.

L-arginine plays a critical role in regulating the immune system (1-3). In inflammation, cancer and certain other pathological conditions, myeloid cell differentiation is inhibited leading to a heterogeneous population of immature myeloid cells, known as myeloid-derived suppressor cells (MDSCs) (4). MDSCs are recruited to sites of cancer-associated inflammation and express high levels of arginase-1 (4). Arginase-1 catalyzes the final step of the urea cycle converting L-arginine to L-ornithine and urea (5). Thus MDSCs increase the catabolism of L-arginine resulting in L-arginine depletion in the inflammatory microenvironment of cancer (4, 6). The reduced availability of L-arginine suppresses T-cell proliferation and function and thus contributes to tumor progression (4, 6). Arginase-1 is of great interest to researchers looking for a therapeutic target to inhibit the function of MDSCs in the context of cancer immunotherapy (7). In addition, research studies have demonstrated that Arginase-1 distinguishes primary hepatocellular carcinoma (HCC) from metastatic tumors in the liver, indicating its value as a potential biomarker in the diagnosis of HCC (8, 9).
