Intra-assay Precision (Precision within an assay): CV%<8%
Three samples of known concentration were tested twenty times on one plate to assess.
Inter-assay Precision (Precision between assays): CV%<10%
Three samples of known concentration were tested in twenty assays to assess.
To assess the linearity of the assay, samples were spiked with high concentrations of rat sCD14 in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.

Target Background

(From Uniprot)
Coreceptor for bacterial lipopolysaccharide. In concert with LBP, binds to monomeric lipopolysaccharide and delivers it to the LY96/TLR4 complex, thereby mediating 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. Acts as a coreceptor for TLR2:TLR6 heterodimer in response to diacylated lipopeptides and for TLR2:TLR1 heterodimer in response to triacylated lipopeptides, these clusters trigger signaling from the cell surface and subsequently are targeted to the Golgi in a lipid-raft dependent pathway. Binds electronegative LDL (LDL(-)) and mediates the cytokine release induced by LDL(-).

  1. This study shows that sCD14 impairs contractile function and insulin action in primary adult rat cardiomyocytes. PMID: 27816522
  2. CD 14 mRNA expression increased significantly after five days of bile duct ligation in liver, lung, spleen, and ileum. PMID: 25093541
  3. biliary drainage affects expression of inducible nitric oxide synthase, CD14 and TGR5 expression in obstructive jaundice rats PMID: 23613625
  4. Burn injury-induced mitochondrial damage in cardiomyocytes was prevented in CD14 knockout mice. Burn injury produces CD14-dependent mitochondrial damage via oxidative stress in myocardium. PMID: 20348223
  5. Acute cerebral hemorrhage results in endotoxemia and widespread increases in CD14 and IL-1beta expression. PMID: 19534684
  6. Expression of CD14 protein and its gene in liver sinusoidal endothelial cells during endotoxemia. PMID: 12046090
  7. Increase of CD14 mRNA expression may result in greater sensitivity to endotoxin and thus lead to liver injury. PMID: 12113681
  8. Although microglial-derived CD14 does not contribute to early events triggered by intrastriatal endotoxin treatment, it modulates the duration of inflammation within the cerebral tissue. PMID: 12218159
  9. Ethanol administration led to a significant synthesis of endotoxin receptor CD14 protein and its gene expression in Kupffer cells, which maybe result in the pathological changes of liver tissue and hepatic functional damages. PMID: 12632533
  10. the CD14 antigen system appeared to be an early trigger for Kupffer cell activation followed by induction of inflammatory cytokine interleukin-1beta synthesis leading to hepatic injury after partial hepatectomy PMID: 14572767
  11. CD14 glycoprotein is present on the cell membranes of vascular smooth muscle cells of rat aorta, where it acts as a lipopolysaccharide receptor. PMID: 15153652
