Precision
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.
Linearity
To assess the linearity of the assay, samples were spiked with high concentrations of human eotaxin 2/CCL24 in various matrices and diluted with the Sample Diluent to produce samples with values within the dynamic range of the assay.

Target Data

Function Chemotactic for resting T-lymphocytes, and eosinophils. Has lower chemotactic activity for neutrophils but none for monocytes and activated lymphocytes. Is a strong suppressor of colony formation by a multipotential hematopoietic progenitor cell line. Binds to CCR3.
Gene References into Functions
  1. Study showed that CCL24 was upregulated in hepatocellular carcinoma (HCC) tissues and correlated with poor prognosis in HCC patients . Also, CCL24 was associated with the metastatic potential of HCC cell lines and promoted proliferation, migration, and invasion. PMID: 28042950
  2. Mean eotaxin 2 concentrations in nasal fluid in patients with perennial allergic rhinitis and nonallergic and allergic chronic rhinosinusitis with nasal polyps patients were significantly higher in comparison to control subjects. PMID: 28587510
  3. HMGB1 did not elicit chemotaxis of human eosinophils alone and had no effect in combination with the eosinophil chemotactic agent, eotaxin-2 (CCL24). PMID: 25774667
  4. these data suggest that CCL26 and CCL24 are likely involved in the pathogenesis of chronic nasal hypereosinophilia, with a complex cooperation and different involvement of the various members of eotaxin family. PMID: 24989688
  5. Pregnancy associated environments increased local CCL24/CCR3, supporting the process of decidualization in human early pregnancy. PMID: 23696919
  6. Phosphodiesterase 4 inhibitors, rolipram and RO-20-1724 have no effect on CCL24 expression in human primary bronchial epithelial cells. PMID: 22946025
  7. Study shows that CCL24 levels were significantly increased in age-related macular degeneration (AMD) patients despite Avastin treatment as compared with normal controls and those without Avastin. PMID: 23025269
  8. CCR3 is differentially expressed on inflammatory cells in rheumatoid arthritis, while eotaxin-2, a potent CCR3 agonist, is differentially expressed in active disease. PMID: 20659406
  9. stimulates lung fibroblast proliferation and collagen synthesis PMID: 20143648
  10. alters eosinophil integrin function via mitogen-activated protein kinases PMID: 12034562
  11. Intradermal injection of CCL24 induces recruitment of eosinophils, basophils, neutrophils, and macrophages as well as features of early- and late-phase allergic reactions in atopic and nonatopic volunteers. PMID: 12193745
  12. Plasma eotaxin-2 concentrations differed in asthmatic patients with respect to aspirin intolerance and tolerance, indicating that eotaxin-2 may be differentially up-regulated according to aspirin intolerance. PMID: 16304252
  13. Our results suggest that Eo2 +179T>C and Eo2 +275C>T of eotaxin-2 might be associated with the susceptibility of ulcerative colitis. PMID: 16391516
  14. These data support the idea that CCL24/eotaxin-2 is part of the mechanism of CD4 lymphocyte activation paracrinally induced by Nef. PMID: 17630924
  15. eotaxin-2 is a chemokine strongly associated with primary and metastatic tumors of colorectal origin PMID: 17908961
  16. the ability to produce eotaxin-2/CCL24 is acquired during the differentiation into eosinophilic lineage which is dependent on GATA-1 expression PMID: 17917245
  17. This protein is an eosinophil chemoattractant that is up-regulated by human rhinovirus infection in cultured bronchial epithelial cells. PMID: 11467997
