Applications

Recommended Concentration
Sample
Western Blot
2 µg/mL
Human peripheral blood mononuclear cells (PBMC)
Flow Cytometry
0.25 µg/106 cells
See below
CyTOF-ready
Ready to be labeled using established conjugation methods. No BSA or other carrier proteins that could interfere with conjugation.
 
Neutralization
Measured by its ability to neutralize lipopolysacharide (LPS)-induced TNF‑ alpha secretion in the THP-1 human acute monocytic leukemia cell line. At 10 µg/mL, this anti-hCD14 antibody will neutralize >60% of 0.5 ng/mL LPS-induced TNF-alpha secretion.

Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.

Data Examples

Western Blot View Larger

Detection of Human CD14 by Western Blot. Western blot shows lysates of human peripheral blood mononuclear cells (PBMC). PVDF membrane was probed with 2 µg/mL of Mouse Anti-Human CD14 Monoclonal Antibody (Catalog # MAB3832) followed by HRP-conjugated Anti-Mouse IgG Secondary Antibody (HAF018). A specific band was detected for CD14 at approximately 55 kDa (as indicated). This experiment was conducted under non-reducing conditions and using Western Blot Buffer Group 1.

Background: CD14

CD14 is a 55 kDa cell surface glycoprotein that is preferentially expressed on monocytes/macrophages. The human CD14 cDNA encodes a 375 amino acid (aa) residue precursor protein with a 19 aa signal peptide and a C-terminal hydrophobic region characteristic for glycosylphosphatidyinositol (GPI)-anchored proteins. Human CD14 has four potential N-linked glycosylation sites and also bears O-linked carbohydrates. The amino acid sequence of human CD14 is approximately 65% identical with the mouse, rat, rabbit, and bovine proteins. CD14 is a pattern recognition receptor that binds lipopolysaccharides (LPS) and a variety of ligands derived from different microbial sources. The binding of CD14 with LPS is catalyzed by LPS-binding protein (LBP). The toll-like-receptors have also been implicated in the transduction of CD14-LPS signals. Similar to other GPI-anchored proteins, soluble CD14 can be released from the cell surface by phosphatidyinositol-specific phospholipase C. Soluble CD14 has been detected in serum and body fluids. High concentrations of soluble CD14 have been shown to inhibit LPS-mediated responses. However, soluble CD14 can also potentiate LPS response in cells that do not express cell surface CD14.
