General description

S100A8, also known as Protein S100-A8, Calgranulin-A, Calprotectin L1L subunit, Cystic fibrosis antigen (CFAG), Leukocyte L1 complex light chain, Migration inhibitory factor related protein 8 (MRP-8), p8, S100 calcium binding protein A8, or Urinary stone protein band A, and encoded by the gene S100A8/CAGA/CFAG/MRP8, is an important protein that binds both zinc and calcium and plays an important role in the regulation of inflammatory processes and immune response. Found in complex with its partner S100A9, S100A8 facilitates chemotaxis, fatty acid trafficking, cytoskeleton reorganization, and NAPDPH oxidase activation and other intracellular activities, as well as a host of extracellular induced activities such as extracellular proinflammatory, antimicrobial, oxidant scavenging, and apoptotic activities . Additionally S100A8 can act as a potent autoimmunity amplifier and appears to augment various cancers and their spread when over expressed. S100A8 is widely expressed and used as biomarker in patients with inflammatory diseases and as a cancer marker in multiple forms of cancer.

Specificity

This antibody detects both S100A8 and S100A9.

Immunogen

Whole cells expressing Human S100A8 & S100A9.

This Anti-S100A8/S100A9 Antibody, clone 5.5 is validated for use in Flow Cytometry and Immunoprecipitation and Immunohistochemistry and ELISA and Western Blotting for the detection of S100A8/S100A9.
Western Blotting Analysis: A representative lot of this antibody was used to detect S100A8/S100A9 in Human monocyte and neutrophil extracts (Edgeworth, J., et al., (1991) JBC. 266(12):7706-7713).
Western Blotting Analysis: A representative lot of this antibody was used to detect S100A8/S100A9 in neutrophil extracts (Hogg et al., 1989).
Immunoprecipitation Analysis: A representative lot of this antibody was used to detect S100A8/S100A9 in Human monocyte and neutrophil lysate (Edgeworth, J., et al., (1991) JBC. 266(12):7706-7713).
Immunoprecipitation Analysis: A representative lot of this antibody was used to detect S100A8/S100A9 in MRP-8 and TL-14 mutant lysate (Hessian P.A., et al., (2001) Eur. J. Biochem. 268:353-363).
Immunohistochemistry Analysis: A representative lot of this antibody was used to detect S100A8/S100A9 in Human Bronchus tissue (Hogg, N., et al., (1989) Eur. J. Immunol. 19:1053-1061).
Immunohistochemistry Analysis: A representative lot of this antibody was used to detect S100A8/S100A9 in spleen and thymus tissue (Hogg, N., et al., (1989) Eur. J. Immunol. 19:1053-1061).
ELISA: A representative lot of this antibody was used to detect S100A8/S100A9 in ELISA (Ryckman, C., et al., (2003) Arthritis & Rheumatism. 48(8):2310-2320).

Quality

Evaluated by Flow Cytometry on Human PBMCs.
