- BACKGROUND
Description | 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-kappaB. 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 331 amino acid glycoprotein comprising the extracellular portion of the CD14 receptor. |
---|---|
BiologicalActivity | Determined by the dose dependent activation of NF-kappaB in a RAW264 cell line based reporter system, using a sCD14 concentration range of 20 ng/μl to 200 ng/μl. The NF-kappaB activation is enhanced when the assay is done in the presence of 0.25 ng/μl to 1.0 ng/μl bacterial LPS. |
Authenticity | Verified by N-terminal and Mass Spectrometry analyses (when applicable). |
Endotoxin | Endotoxin level is <0.1 ng/ µg of protein (<1EU/ µg). |
Protein Content | Verified by UV Spectroscopy and/or SDS-PAGE gel. |
Storage | -20°C |
Precautions | Recombinant Human sCD14 is for research use only and not for use in diagnostic or therapeutic procedures. |
