WB Use at an assay dependent concentration. Detects a band of approximately 35 kDa (predicted molecular weight: 35 kDa).
IP Use at an assay dependent concentration.


  • Pathway

    Nitrogen metabolism; urea cycle; L-ornithine and urea from L-arginine: step 1/1.
  • Involvement in disease

    Defects in ARG1 are the cause of argininemia (ARGIN) [MIM:207800]; also known as hyperargininemia. Argininemia is a rare autosomal recessive disorder of the urea cycle. Arginine is elevated in the blood and cerebrospinal fluid, and periodic hyperammonemia occurs. Clinical manifestations include developmental delay, seizures, mental retardation, hypotonia, ataxia, progressive spastic quadriplegia.
  • Sequence similarities

    Belongs to the arginase family.

  • Lane 1 (input): Human fetal liver whole cell lysate, 10μg
    Lane 2: Human fetal liver whole cell lysate
    Lane 3: Rabbit monoclonal IgG (ab172730) instead of ab133543 in Human fetal liver whole cell lysate

    Ab133543 immunoprecipitating liver arginase in Human fetal liver whole cell lysates. Primary antibody was used at a 1:1000 dilution (0.27 μg/ml). For western blotting, VeriBlot for IP Detection Reagent (HRP) (ab131366), was used for detection at 1/5000 dilution.  Capture antibody was used at 1:20 dilution (1.3μg in 0.35mg lysates).

    Blocking and diluting buffer used: 5% NFDM/TBST.

    This data was developed using the same antibody clone in a different buffer formulation containing PBS, BSA, glycerol, and sodium azide (ab133543).

  • This IHC data was generated using the same anti-Liver Arginase antibody clone, EPR6672(B), in a different buffer formulation (cat# ab133543).

    Immunohistochemical analysis of paraffin embedded Human hepatocellular carcinoma tissue labelling liver Arginase with ab133543 antibody at a dilution of 1/250.
