This Antibody was verified by Cell treatment to ensure that the antibody binds to the antigen stated.
Description: The monoclonal antibody A1exF5 recognizes both human and mouse Arginase 1, a cytosolic enzyme (Arg1). This A1exF5 clone is compatible with both the standard intracellular protocols and the Foxp3/Transcription Factor Staining Buffer Set.
Applications Reported: This A1exF5 antibody has been reported for use in flow cytometric analysis.
Applications Tested: This A1exF5 antibody has been tested by flow cytometric analysis of normal human peripheral blood cells using the Intracellular Fixation & Permeabilization Buffer Set (Product # 88-8824) and protocol. Please refer to Best Protocols: Protocol A: Two step protocol for (cytoplasmic) intracellular proteins located under the Resources Tab online. This may be used at less than or equal to 0.5 µg per test. A test is defined as the amount (µg) of antibody that will stain a cell sample in a final volume of 100 µL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. It is recommended that the antibody be carefully titrated for optimal performance in the assay of interest.
Excitation: 488-561 nm; Emission: 578 nm; Laser: Blue Laser, Green Laser, Yellow-Green Laser
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.
