Anti-Arginase-1, clone 3B17 ZooMAb^®, Cat. No. ZRB1088, is a recombinant Rabbit monoclonal antibody that targets Arginase-1 and is tested for use in Affinity Binding Assay, Flow Cytometry, Immunohistochemistry (Paraffin), and Western Blotting.

Arginase-1 (UniProt: P05089; also known as EC:3.5.3.1, Liver-type arginase, Type I arginase) is encoded by the ARG1 gene (Gene ID: 383) in human. Arginase-1 is a manganese-containing liver enzyme that participates in urea cycle and converts L-arginine to urea and L-ornithine. It also functions to maintain L-arginine homeostasis in non-hepatic tissues where nitric oxide synthase (NOS) and arginase compete for the available intracellular arginine. Arginase-1 is also Involved in an antimicrobial effector pathway in polymorphonuclear granulocytes (PMN). Upon PMN cell death, it is liberated from the phagolysosome and depletes arginine in the microenvironment leading to suppressed T cell and natural killer (NK) cell proliferation and cytokine secretion. Although expression of arginase-1 is commonly associated with inflammation, fibrosis, and wound healing involving increased L-proline, polyamine, and Th2 cytokine production, macrophage-specific arginase-1 is reported to act as an inhibitor of inflammation and fibrosis following infection with the Th2-inducing pathogens. In murine species, arginase is induced in myeloid cells mainly by Th2 cytokines and inflammatory agents and participates in a variety of inflammatory diseases by down-regulation of nitric oxide synthesis, induction of fibrosis and tissue regeneration. Mutations in ARG1 gene are associated with Aargininemia that is characterized by elevated levels of arginine in the blood and cerebrospinal fluid, developmental delays, seizures, and mental retardation. This ZooMAb^® recombinant monoclonal antibody, generated by our propriety technology, offers significantly enhanced specificity, affinity, reproducibility, and stability over conventional monoclonals.
