S100A8/A9 Complex (Calprotectin) antibody (Biotin)

Catalog No. ABIN111883

Product Details anti-S100A8/A9 Complex (Calprotectin) Antibody (Biotin)

Target: S100A8/A9 Complex (Calprotectin) (S100A8/A9) (S100 Calcium Binding Protein A8/A9 (S100A8/A9))

Reactivity: Human

Host: Mouse

Clonality: Monoclonal

Conjugate: This S100A8/A9 Complex (Calprotectin) antibody is conjugated to Biotin

Application: Immunohistochemistry (Paraffin-embedded Sections) (IHC (p)), Enzyme Immunoassay (EIA), Immunohistochemistry (Frozen Sections) (IHC (fro))

Specificity: This antibody is ideally suited for the detection of early inflammatory macrophages and thus for the classification of acute stage inflammation in tissue sections and in smears, the characterization of tumorous tissues and the in vitro monitoring of peripheral blood cell cultures. Clone 27E10 is unique in that it recognizes an epitope on the MRP8/14 heterocomplex that is not exposed on the individual subunits MRP8 or MRP14. The antibody reacts with Human subpopulations of macrophages, monocytes and granulocytes, peripheral blood monocytes carry the antigen extra- and intracellularly, neutrophils only intracellularly. Antigen Distribution Isolated Cells: Monocytes carry the antigen both on the surface and intracellularly, granulocytes exhibit it only intracellularly. Up to 80 % of monocytes in early cultures (24-48h) are positive. No reaction has been seen with lymphocytes or platelets. Tissue Sections: The antigen is found in macrophages in the red pulp of the spleen and liver. It is strongly expressed in macrophages from acute inflamed tissues (peridontitis, contact eczema, urticaria, erythrodermia) where some endothelial and epidermal cells may also express this antigen. It is normally absent on resident mononuclear phagocytes in healthy tissues (skin, gut, thymus).

Cross-Reactivity (Details): Species reactivity (tested):Human. The antibody also stains a subpopulation of macrophages of Rhesus Monkey and Bovine tissues. It does not react with Swine tissues.

Purification: Affinity Chromatography.

Immunogen: Cultured Human monocytes. Remarks: The antigen is MRP8/14 (Calprotectin), the epitope involves parts of both subunits MRP8 and MRP14.

Clone: 2-70E-011

Isotype: IgG1

Application Details

Application Notes: Suitable for use in Immunohistochemistry (IHC) on : Frozen sections: 0.5 μg/mL (1/400)Paraffin sections: 2 μg/mL (1/100). Proteinase K pretreatment for antigen retrieval isrecommended. Suggested positive control: Human tonsil. Also suitable for Flow cytometrya and ELISA. Antigen distribution on Isolated cells and Tissue sections: Monocytes carry the antigenboth on thesurface and intracellularly, granulocytes exhibit it onlyintracellularly. Up to 80 % of monocytes in early cultures (24-48h) are positive. No reactionhas been seen with lymphocytes or platelets. The antigen is found in macrophages in the red pulp of the spleen and liver. It is stronglyexpressed in macrophages from acute inflamed tissues (peridontitis, contacteczema, urticaria, erythrodermia) where some endothelial andepidermal cells may also express this antigen. It is normally absent on residentmononuclear phagocytes in healthy tissues (skin, gut, thymus).

Target Details for S100A8/A9 Complex (Calprotectin)

Target: S100A8/A9 Complex (Calprotectin) (S100A8/A9) (S100 Calcium Binding Protein A8/A9 (S100A8/A9))

Alternative Name: MRP8 / MRP14 (S100A8/A9 Products)

Synonyms: 60B8AG antibody, CAGB antibody, CFAG antibody, CGLB antibody, L1AG antibody, LIAG antibody, MAC387 antibody, MIF antibody, MRP14 antibody, NIF antibody, P14 antibody, S100 calcium binding protein A9 antibody, S100A9 antibody

Background: MRP8 and MRP14 are members of the S100 family of proteins containing 2 EF hand calcium binding motifs. S100 proteins are localized in the cytoplasm and/or nucleus of a wide range of cells, and involved in the regulation of a number of cellular processes such as cell cycle progression and differentiation. S100 genes include at least 13 members which are located as a cluster on chromosome 1q21. The antigen is produced by the heterocomplex formation of MRP8 (S100A8 or Calgranulin A) and MRP14 (S100A9 or Calgranulin B), two calcium binding proteins of the S 100 protein family.Synonyms: CAGA, CAGB, CFAG, Calgranulin A/B, Calprotectin, L1 Protein, MRP-14, MRP-8, P14, P8
