Description
| Product Name: | Human CD14 Recombinant Protein |
| Product Code: | RPPB3004 |
| Size: | 50µg |
| Species: | Human |
| Target: | CD14 |
| Synonyms: | Monocyte differentiation antigen CD14, Myeloid cell-specific leucine-rich glycoprotein, CD14. |
| Source: | Chinese Hamster Ovary Cells (CHO) |
| Physical Appearance: | Sterile Filtered White lyophilized (freeze-dried) powder. |
| Formulation: | CD14 was lyophilized from a concentrated protein solution (1.0 mg/ml) containing phosphate-buffered saline, pH 7.2. |
| Solubility: | It is recommended to reconstitute the lyophilized CD14 in sterile 18M?-cm H2O not less than 100�g/ml. Further dilutions should be made with phosphate buffered saline (PBS). |
| Stability: | Lyophilized CD14 although stable at room temperature for 3 weeks, should be stored desiccated below -18°C. Upon reconstitution CD14 should be stored at 4°C between 2-7 days and for future use below -18°C.For long term storage it is recommended to add a carrier protein (0.1% HSA or BSA).Please prevent freeze-thaw cycles. |
| Purity: | Greater than 95.0% as determined by SDS-PAGE. |
| Biological Activity: | Up to 20 �g/ml CD14 inhibit binding of FITC-LPS (0.5�g/ml) to 600,000 CD14+CHO transfectants (FACS). |
CD14 (also known lipopolysaccharide (LPS) receptor) 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. CD14 has been shown to bind apoptotic cells.
The CD14 is produced from human CD14 transfected CHO-cells. Before transfection the complete human CD14-cDNA was amplified by PCR and cloned into expression vector p-POL-DHFR. The myeloid differentiation antigen CD14 acts as the major receptor for bacterial LPS. The dominant form of the recombinant wild type CD14 is the 50-kDa protein containing 335 amino acids and lacks the GPI-Anchor.
| UniProt Protein Function: | CD14: Cooperates with MD-2 and TLR4 to mediate 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 Protein Details: | Protein type:Membrane protein, GPI anchor Cellular Component: anchored to external side of plasma membrane; extracellular space; cell surface; membrane; plasma membrane; lipopolysaccharide receptor complex; lipid raft; external side of plasma membrane Molecular Function:lipopolysaccharide binding Biological Process: response to bacterium; immune system process; response to molecule of bacterial origin; innate immune response; positive regulation of endocytosis; positive regulation of tumor necrosis factor production; inflammatory response; positive regulation of cytokine secretion |
| NCBI Summary: | This gene encodes a protein that plays an important role in the innate immune response and is expressed in monocyte/macrophage cells. This gene product acts as a co-receptor that binds several microbial and fungal molecules, including lipopolysaccharides (LPS). This proteins LPS-binding activity is enhanced by the LPS binding protein (LBP) to allow binding to the TLR4-MD-2 co-receptor complex. The product of this gene is found in two forms, either as a soluble protein or attached to the cell surface by a glycosylphosphatidylinositol anchor. [provided by RefSeq, Jul 2014] |
