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 human RNASE2 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)
This is a non-secretory ribonuclease. It is a pyrimidine specific nuclease with a slight preference for U. Cytotoxin and helminthotoxin. Selectively chemotactic for dendritic cells. Possesses a wide variety of biological activities.
Gene References into Functions
  1. In healthy children, 95th Percentile values ranged from 1519 mg/kg at 0 months to 54.4 mg/kg at 144 months for fecal calprotectin (fCP) and from 9.9 mg/kg at 0 months to 0.2 mg/kg at 144 months for fecal eosinophil-derived neurotoxin (fEDN). There was a significant association between age and fCP concentrations and age and fEDN concentrations and a significant association between fEDN and fCP. PMID: 28169973
  2. EDN serum level could be considered a candidate molecule as a clinical biomarker for evaluating atopic dermatitis activity and a predictor of relapse PMID: 28866306
  3. Serum EDN level may be a useful marker for monitoring persistent airflow limitation in adult patients with asthma who had positive results for house-dust-specific IgE antibodies. PMID: 26534742
  4. increased in feces after the ingestion of enterocolitis-causative foods PMID: 24890227

  6. The antimicrobial protein, RNase 2 exhibits antiviral against respiratory syncytial virus. PMID: 9826755
  7. findings show substantial amounts of EPX/EDN localise in an extra-granular, low equilibrium density compartment of eosinophils PMID: 23053729
  8. A higher level of serum EDN was found specifically in patients with ALS, indicating that EDN may participate in the pathophysiology of Amyotrophic lateral sclerosis. PMID: 23533305
  9. Eosinophil protein X in urine from asymptomatic neonates is a biomarker significantly associated with later development of allergic sensitization, nasal eosinophilia, and eczema during the first 6 years of life PMID: 21680952
  10. atomic resolution structure PMID: 11876642
  11. crystal structure of a post-translationally modified form of eosinophil-derived neurotoxin (EDN) with four extra residues on its N terminus ((-4)EDN) has been solved and refined at atomic resolution (1 A) PMID: 11916383
  12. EDN and ECP are paralogs in human and Old World monkeys. PMID: 11959927
  13. evidence for glycosylphosphatidylinositol (GPI)-anchored neurotoxin on granulocytes PMID: 12606041
  14. data suggest that peripheral blood eosinophils from subjects with untreated asthma have increased inflammatory capacity, as reflected by greater intracellular concentrations of EDN PMID: 15356558
  15. Results reveal the dendritic cell-activating activity of eosinophil-derived neurotoxin and suggest that it is a likely participant of inflammatory and immune responses--an endogenous multifunctional immune alarmin. PMID: 15528350
  16. Results describe the crystal structure of placental ribonuclease inhibitor in complex with eosinophil-derived neurotoxin, and a mutational analysis based on this structure. PMID: 15755456
  17. May possibly be associated with the development of tropical pulmonary eosinophilia. PMID: 16014847
  18. Elevated glycosylated form of EDN in urine is associated with ovarian cancer PMID: 16428483
  19. EGO is a novel ncRNA gene expressed during eosinophil development and is necessary for normal MBP and EDN transcript expression. PMID: 17351112
  20. Data show that uEPX/c levels did not correlate with established markers of asthma severity and eosinophilic airway inflammation in atopic asthmatic children. PMID: 17641730
  21. MAZ and Sp1 play important roles on the transcriptional activation of the human edn promoter through specific binding to a 34-nt segment present in representative primate eosinophil rnase promoters. PMID: 17927842
  22. Urinary concentrations of eosinophil-derived neurotoxin in patients with atopic dermatitis show a significant positive correlation with disease severity. PMID: 17965582
  23. EDN can activate myeloid DCs by triggering the Toll-like receptor (TLR)2-myeloid differentiation factor 88 signaling pathway PMID: 18195069
  24. In three continental population groups (Asia, Europe, Africa), the angiogenin and RNase 2 genes appear to exhibit markedly less genetic heterogeneity with regard to T195C and A238G (ANG) and C425A (RNASE2) SNPs. PMID: 18636464
  25. No variation in genes encoding eosinophil-derived neurotoxin for Atopic dermatitis pathogenesis in this German cohort. PMID: 19014520
