Scientific Data Images for Human CD14 Antibody
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.
Detection of CD14 in Human PBMCs by Flow Cytometry.
Human peripheral blood mononuclear cells (PBMCs) were stained with Mouse Anti-Human CD14 Monoclonal Antibody (Catalog # MAB3832) followed by Goat anti-Mouse IgG APC-conjugated Secondary Antibody (Catalog # F0101B). View our protocol for Staining Membrane-associated Proteins.
Detection of CD14 in human tonsil.
CD14 was detected in immersion fixed paraffin-embedded sections of human tonsil using Mouse Anti-Human CD14 Monoclonal Antibody (Catalog # MAB3832) at 5 µg/mL for 1 hour at room temperature followed by incubation with the Anti-Mouse IgG VisUCyte™ HRP Polymer Antibody (Catalog # VC001). Before incubation with the primary antibody, tissue was subjected to heat-induced epitope retrieval using VisUCyte Antigen Retrieval Reagent-Basic (Catalog # VCTS021). Tissue was stained using DAB (brown) and counterstained with hematoxylin (blue). Specific staining was localized to cell surface in lymphocytes.

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.

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.
