Anti-S100A9 antibody produced in rabbit

S100A9 is a small calcium-binding protein belonging to the low-molecular weight S100 protein family. It is highly expressed in the neutrophil, monocyte cytosol and adipose tissues. During inflammation it is found at high concentration in extracellular milieu.

Protein S100-A9 recombinant protein epitope signature tag (PrEST)

Anti-S100A9 antibody produced in rabbit, a Prestige Antibody, 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. The antibodies are also tested using immunofluorescence and western blotting. To view these protocols and other useful information about Prestige Antibodies and the HPA, visit sigma.com/prestige.

S100A9 (S100 calcium binding protein A9) has pro-inflammatory action in acute and chronic inflammation. In addition to inflammatory action, it exhibits cytokine-like activities for the activation of receptor for advanced glycation end products (RAGE) and Toll-like receptor 4-dependent signaling cascades. S100A9 stimulates neutrophil chemotaxis. It stimulates shedding of L-selectin, up-regulates and activates Mac-1 which finally induce neutrophil adhesion to fibrinogen in vitro.

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.

Solution in phosphate-buffered saline, pH 7.2, containing 40% glycerol and 0.02% sodium azide
