S100 Calcium Binding Protein A9 (S100A9, 60B8AG, Calgranulin B, CAGB, Calprotectin L1H Subunit, CFAG, CGLB, Cystic Fibrosis Antigen, L1AG, Leukocyte L1 Complex Heavy Chain, LIAG, MAC387, Migration Inhibitory Factor-related Protein 14, MIF Related Protein
The calcium-binding, migration inhibitory factor-related proteins, MRP-8 (S100A8) and MRP-14 (S100A9) belong to the S100 protein family. The expression of these proteins is largely confined to the cytosol of neutrophils and monocytes. The complex formation of these proteins is a calcium-dependent process. The S100A8/A9 heterocomplex, also called MRP-8/MRP-14 complex or calprotectin, comprises 60% of the cytoplasmic protein fraction of circulating polymorphonuclear granulocytes and is also found in monocytes, macrophages and ileal tissue eosinophils. In inflammatory conditions small venueles stain with both anti-S100A8 and S100A9. The staining of the two subunits is always coincident. The S100A8/A9 complex has antibacterial, antifungal and immunomodulating and antiproliferative effects. Besides this it is a potent chemotactic factor for neutrophils.

Can be used for Western Blot and Flow Cytometry. Furthermore the antibody is useful for immunoassays as detector.

Recommended Dilution:
Flow Cytometry: 1:10
Western Blot: 1:10
Optimal dilutions to be determined by the researcher.

Storage and Stability:
May be stored at 4C for short-term only. For long-term storage and to avoid repeated freezing and thawing, aliquot and add glycerol (40-50%). Store at -20C or colder. Aliquots are stable for at least 12 months at -20C. For maximum recovery of product, centrifuge the original vial after thawing and prior to removing the cap. Further dilutions can be made in assay buffer.
