- 特异性
- This monoclonal 27E10 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: A subpopulation of monocytes and neutrophilic granulocytes are positive. 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 in the liver, strongly expressed on macrophages in acute inflamed tissues (peridontitis, contact excema, urticaria, erythrodermia) where some endothelial and epidermal cells may also express this antigen, absent on normal resident mononuclear phagocytes in healthy tissues (skin, gut, thymus).Antigen Distribution
- 交叉反应 （详细）
- 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.
- 纯化方法
- Affinity Chromatography on Protein G
- 免疫原
- Cultured Human monocytes. Remarks: The antigen is MRP8/14 (Calprotectin), the epitope involves parts of both subunits MRP8 and MRP14.
