| Application Note | WB: Under non-reducing condition. ELISA: The clone MEM-18 has been tested as the detection antibody in a sandwich ELISA for analysis of human CD14 in combination with clone B-A8 (ARG62727). Functional studies: The clone MEM-18 completely blocks binding of fluorescein (FITC) - labeled bacterial LPS to the monocyte surface and it also blocks the binding of CD14 to the extracellular TLR2 domain. * The dilutions indicate recommended starting dilutions and the optimal dilutions or concentrations should be determined by the scientist. |

Swiss-port # P08571 Human Monocyte differentiation antigen CD14 |
|---|---|
| Gene Symbol | CD14 |
| Gene Full Name | CD14 molecule |
| Background | CD14 is a 55 kDa GPI-anchored glycoprotein, constitutively expressed on the surface of mature monocytes, macrophages, and neutrophils, where serves as a multifunctional lipopolysaccharide receptor; it is also released to the serum both as a secreted and enzymatically cleaved GPI-anchored form. CD14 binds lipopolysaccharide molecule in a reaction catalyzed by lipopolysaccharide-binding protein (LBP), an acute phase serum protein. The soluble sCD14 is able to discriminate slight structural differences between lipopolysaccharides and is important for neutralization of serum allochthonous lipopolysaccharides by reconstituted lipoprotein particles. CD14 affects allergic, inflammatory and infectious processes. |
| 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. [UniProt] |
