    Unsuitable for: IHC-G or IHC-P
  • Species reactivity
    Reacts with: Human, Monkey
    Does not react with: Rat, Guinea pig, Pig
  • Immunogen

    Human monocytes (epitope recognized SRCR domain 9).

  • Positive control
    • ICC/IF: M2-type tumor-associated macrophages. Human placenta. CHO-cells transfected with CD163.
  • General notes


    ab17051 is very useful for macrophage phenotyping. Positive staining can be seen in the skin (histiocytes), gut, Kupffer cells, few aveolar macrophages, main population of macrophages in the placenta, varying degrees of macrophages in inflammed tissue including tumorous tissue depending on the inflammatory stage. Red pulp, not white pulp, macrophages in the spleen and cortical macrophages of the thymus are detected. Antibody is sensitive to ionic detergents and to chloroform/methanol treatment.

  • Target

    • Function
      Acute phase-regulated receptor involved in clearance and endocytosis of hemoglobin/haptoglobin complexes by macrophages and may thereby protect tissues from free hemoglobin-mediated oxidative damage. May play a role in the uptake and recycling of iron, via endocytosis of hemoglobin/haptoglobin and subsequent breakdown of heme. Binds hemoglobin/haptoglobin complexes in a calcium-dependent and pH-dependent manner. Exhibits a higher affinity for complexes of hemoglobin and multimeric haptoglobin of HP*1F phenotype than for complexes of hemoglobin and dimeric haptoglobin of HP*1S phenotype. Induces a cascade of intracellular signals that involves tyrosine kinase-dependent calcium mobilization, inositol triphosphate production and secretion of IL6 and CSF1. Isoform 3 exhibits the higher capacity for ligand endocytosis and the more pronounced surface expression when expressed in cells.
      After shedding, the soluble form (sCD163) may play an anti-inflammatory role, and may be a valuable diagnostic parameter for monitoring macrophage activation in inflammatory conditions.
    • Tissue specificity
      Expressed in monocytes and mature macrophages such as Kupffer cells in the liver, red pulp macrophages in the spleen, cortical macrophages in the thymus, resident bone marrow macrophages and meningeal macrophages of the central nervous system. Expressed also in blood. Isoform 1 is the lowest abundant in the blood. Isoform 2 is the lowest abundant in the liver and the spleen. Isoform 3 is the predominant isoform detected in the blood.
    • Sequence similarities
      Contains 9 SRCR domains.
    • Domain
      The SRCR domain 3 mediates calcium-sensitive interaction with hemoglobin/haptoglobin complexes.
    • Post-translational
      modifications
      A soluble form (sCD163) is produced by proteolytic shedding which can be induced by lipopolysaccharide, phorbol ester and Fc region of immunoglobulin gamma. This cleavage is dependent on protein kinase C and tyrosine kinases and can be blocked by protease inhibitors. The shedding is inhibited by the tissue inhibitor of metalloproteinase TIMP3, and thus probably induced by membrane-bound metalloproteinases ADAMs.
      Phosphorylated.
    • Cellular localization
      Secreted and Cell membrane. Isoform 1 and isoform 2 show a lower surface expression when expressed in cells.
