Clonality Monoclonal
Immunogen Cultured Human monocytes.
Specificity Human MRP14, Granulocytes, stimulated Monocytes and Macrophages:
This clone identifies the Ca2+-binding 14kD subunit of the inflammatory L-1 protein complex, also called S100A9 or Calgranulin B. It is useful for the characterization of circulating granulocytes or inflammatory infiltrates of the myelo-monocytic lineage which express MRP14 differently depending on the inflammatory status of the disease.
Antigen Distribution
Isolated Cells: The antigen is found in granulocytes and monocytes. It is absent from all other blood cells. In cultured monocytes, maximum MRP14 expression is found after 3-4 days. Myeloid leukaemic cells have been found to be positive as well.
Tissue Sections: MRP-14 is found in a distinct subpopulation of inflammatory perivascular infiltrates of the myelo-monocytic lineage. Macrophages synthesise MRP-14 increasingly during the early stages of inflammation. A high MRP-14 (and low MRP-8) expression by macrophages was reported in granulomatous diseases such as tuberculosis and sarcoidis. In non-granulomatous chronic inflammatory diseases like chronic rheumatoid arthritis, MRP8 and MRP14 positive cells consist of different subpopulations. During early inflammation endothelial cells are also positive with MRP8/14 determined by antibody 27E10 (Product Cat.-No BM4025).
Formulation PBS, pH 7.2 containing 5 mg/ml BSA as a stabilizer and 0.05% (v/v) Kathon CG as a preservative

Gene Name S100 calcium binding protein A9
Background S100A9 is a member of the S100 family of proteins. S100A9, together with S100A8 forms a heterodimeric protein complex, Calprotectin, which is a major calcium- and zinc-binding protein in the cytosol of neutrophils, monocytes, and keratinocytes. Complexes of S100A8 and S100A9 are the physiologically relevant forms of these proteins.
S100A9 may function in the inhibition of casein kinase and altered expression of this protein is associated with the disease cystic fibrosis. Its expression and potential cytokine-like function in inflammation and in cancer suggest that S100A8/A9 may play a key role in inflammation-associated cancer.
Synonyms S100-A9, CAGB, MRP-14
