CD14 (Monocyte / Macrophage Marker) Antibody - Without BSA and Azide
Mouse Monoclonal Antibody [Clone LPSR/927 ]
|Application ||IF, FC|
|Other Accession||929, 163867|
|Isotype||Mouse / IgG1, kappa|
|Other Names||Monocyte differentiation antigen CD14, Myeloid cell-specific leucine-rich glycoprotein, CD14, Monocyte differentiation antigen CD14, urinary form, Monocyte differentiation antigen CD14, membrane-bound form, CD14|
|Storage||Store at 2 to 8°C.Antibody is stable for 24 months.|
|Precautions||CD14 (Monocyte / Macrophage Marker) Antibody - Without BSA and Azide is for research use only and not for use in diagnostic or therapeutic procedures.|
|Function||In concert with LBP, binds to monomeric lipopolysaccharide and delivers it to the MD-2/TLR4 complex, thereby mediating the innate immune response to bacterial lipopolysaccharide (LPS). Acts via MyD88, TIRAP and TRAF6, leading to NF-kappa-B activation, cytokine secretion and the inflammatory response. Up-regulates cell surface molecules, including adhesion molecules.|
|Cellular Location||Cell membrane; Lipid-anchor, GPI-anchor.|
|Tissue Location||Expressed strongly on the surface of monocytes and weakly on the surface of granulocytes; also expressed by most tissue macrophages|

Recognizes a protein of 55kDa, identified as CD14 (also known lipopolysaccharide receptor). CD14 is expressed strongly on monocytes and macrophage and weakly on the surface of neutrophils. CD14 is anchored to cells by linkage to glycosylphosphatidylinositol (GPI) and functions as a high affinity receptor for complexes of LPS and LPS binding protein (LBP). Soluble CD14, also binding to LPS, acts at physiological concentration as an LPS agonist and has, at higher concentrations, an LPS antagonizing effect in cell activation.
