General description
The gene S100A8 (S100 calcium-binding protein A8) is mapped to human chromosome 1q21. It is a small calcium-binding protein, which is strongly expressed in neutrophils. In presence of cell stimulation, it is also expressed in monocytes, macrophages, platelets and epithelial and endothelial cells. S100A8 protein is present as a homodimer as well as heterodimer (S100A8/A9). The protein has two EF-hand motifs and one high-affinity Ca2+ binding site. S100A8 is also referred to as myeloid-related protein 8 (MRP8) or calgranulin A.
Immunogen
Protein S100-A8 recombinant protein epitope signature tag (PrEST)
Application
All Prestige Antibodies®Powered by Atlas Antibodies is developed and validated by the Human Protein Atlas (HPA) project . Each antibody is tested by immunohistochemistry against hundreds of normal and disease tissues. These images can be viewed on the Human Protein Atlas (HPA) site by clicking on the Image Gallery link. We also provide Prestige Antibodies® protocols and other useful information.
Anti-S100A8 antibody produced in rabbit has been used in immunohistochemistry and immunofluorescence.
Biochem/physiol Actions
S100A8 (S100 calcium-binding protein A8) is mainly present at the inflammation site or in the serum during acute and chronic inflammation. It is responsible for neutrophil recruitment, attachment and release from the bone marrow. S100A8 is required for sending neutrophils to the site of inflammation in presence of bacterial infection, lipopolysaccharide, and monosodium urate crystals. It is also involved in granulocyte and monocyte attachment to endothelium and also their transport across endothelial cells. The S100A8/A9 heterodimer induces monocyte migration and cytokine secretion. In presence of falciparum malaria, high levels of S100A8 are present in the blood.
Features and Benefits
Prestige Antibodies® are highly characterized and extensively validated antibodies with the added benefit of all available characterization data for each target being accessible via the Human Protein Atlas portal linked just below the product name at the top of this page. The uniqueness and low cross-reactivity of the Prestige Antibodies® to other proteins are due to a thorough selection of antigen regions, affinity purification, and stringent selection. Prestige antigen controls are available for every corresponding Prestige Antibody and can be found in the linkage section.
Every Prestige Antibody is tested in the following ways:
- IHC tissue array of 44 normal human tissues and 20 of the most common cancer type tissues.
- Protein array of 364 human recombinant protein fragments.
Linkage
Corresponding Antigen APREST70709.
Physical form
Solution in phosphate-buffered saline, pH 7.2, containing 40% glycerol and 0.02% sodium azide
