Description

Mouse Monoclonal Antibody

Description: The monoclonal antibody sl6arg recognizes human Arginase-1, a 35 kDa enzyme that that helps eliminate nitrogen by converting L-arginine to urea and L-ornithine which further converts to polyamine. These polyamines are important for cell proliferation and removal of toxins that arise from protein degradation. Expression is found in the liver, neutrophils, as well as myeloid derived suppressor cells (MDSC) and neural stem cells. Expression in macrophages has not been determined in humans, while in mice expression in M2 macrophages is well established. Arginase-1 may be expressed in the myeloid population in breast cancer tumors and is typically found in the majority of hepatocellular carcinomas. Applications Reported: This sl6arg antibody has been reported for use in western blotting, immunohistochemical staining of formalin-fixed paraffin embedded tissue sections, microscopy, immunohistochemical staining, and immunocytochemistry. Applications Tested: This sl6arg antibody has been tested by immunohistochemistry on formalin-fixed paraffin embedded human tissue and can be used at 2 μg/mL. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest. Using conjugate solutions: Centrifuge the protein conjugate solution briefly in a microcentrifuge before use; add only the supernatant to the experiment.

Arginase-1 (Arg1) is a 35 kDa enzyme converting L-arginine to urea and L-ornithine, which is the final step in the urea cycle. The resulting polyamines are important for cell proliferation and removal of toxins that arise from protein degradation. By degrading arginine, Arginase 1 deprives NO synthase of its substrate and down-regulates nitric oxide production. In both human and mouse, Arginase 1 is expressed in the liver, neutrophils, myeloid derived suppressor cells (MDSC) and neural stem cells. In human, expression in blood neutrophils but not in CCR3+ granulocytes has been reported. In mice, expression of Arginase 1 is one of the hallmarks of alternatively activated macrophages (M2a). Arginase-1 may be expressed in the myeloid cells infiltrating tumors, and is typically found in the majority of hepatocellular carcinomas. Defects in Arginase 1 are the cause of argininemia, an autosomal recessive disorder characterized by hyperammonemia.
