特徴

• CD14 is a cell surface anchored glycoprotein that is expressed predominantly by monocytes and tissue macrophages. CD14 associates with MD-2 (LY-96) and TLR4 to form a receptor complex, which signals specifically in response to bacterial lipopolysaccharide (LPS) binding. The CD14/MD-2/TLR4 receptor complex signals via MyD88, TIRAP, and TRAF6, and ultimately activates NF-kappa-beta. CD14 also exists in a soluble form, designated as sCD14, which is capable of specifically binding LPS in the extracellular space. Recombinant sCD14 is a 331aa glycoprotein comprising the extracellular portion of the CD14 receptor.
• Source:Recombinant protein corresponding to human Soluble CD14, expressed in 293 cells.
• Biological Activity:Determined by the dose dependent activation of NF-kappaB in a RAW264 cell line based reporter system, using a sCD14 concentration range of 20ng/ul to 200ng/ul. The NF-kappaB activation is enhanced when the assay is done in the presence of 0.25ng/ul to 1ng/ul bacterial LPS.
• Endotoxin:<0.1ng/ug (1EU/ug)
