Measurement Sandwich
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 IL-1ra 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)
Inhibits the activity of interleukin-1 by binding to receptor IL1R1 and preventing its association with the coreceptor IL1RAP for signaling. Has no interleukin-1 like activity.
Gene References into Functions
  1. IL-1beta is the key trigger of neuroinflammation and that IL-1ra prevents the neuroinflammation entering the chronic state PMID: 24621600
  2. Interleukin-1beta and interleukin-1 receptor antagonist appear in grey matter additionally to white matter during experimental multiple sclerosis PMID: 24376764
  3. Gene expression of the natural IL-1 receptor antagonist IL-1ra and IL-18 (but not TNFalpha) is increased in the ipsilateral hippocampus during long-term potentiation. PMID: 23747799
  4. the IL-1ra gene could be transferred and expressed in corneal tissue efficiently. This may be a novel technique for gene transfection to the cornea in situ. PMID: 22827713
  5. Energy-sensing factors coactivator peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC-1alpha) and AMP-activated protein kinase control expression of inflammatory mediators in liver: induction of interleukin 1 receptor antagonist. PMID: 22117073
  6. IL1Ra has a role in reducing islet endothelial activation and oxidative stress gene expression in the GK diabetic rat PMID: 19742300
  7. IL-1ra, even when applied for only 4 h, reduces neuronal cell death and the number of microglial cells after excitotoxic damage PMID: 15932594
  8. rhIL-1ra may protect renal injury after asphyxia via inhibiting intrarenal inflammatory response. PMID: 16259926
  9. IL-1ra is a modulator of gender differences in the febrile response to lipopolysaccharides. PMID: 17138728
  10. physical training has an effect on IL-1beta, IL-6 and IL-1ra concentrations in various brain areas of the rat PMID: 18299269
  11. Estrogen-induced protection is associated with a decrease in IL-1beta and an increase in IL-1ra expression in the ischemic hippocampus which suggests that modulation of IL-1beta/IL-1ra might be a part of anti-inflammatory effects of estrogen. PMID: 18455872
  12. A pro-inflammatory orientation in the interleukin-1 beta/interleukin-1 receptor antagonist balance might play a role in the initiation of perinatal brain damages. PMID: 18511291
