| 目标/特异性 | Detects canine CXCL8/IL-8 in ELISAs. In ELISAs, this antibody does not cross-react with recombinant feline (rf) CXCL8/IL‑8, rhCXCL8/IL‑8, rpCXCL8/IL‑8, rcaIL‑1 beta /IL‑1F2, or rcaCXCL6/IL‑6. |
| 使用方法 | ELISA Capture (Matched Antibody Pair): 2-8 µg/mL ELISA Detection (Matched Antibody Pair): 0.5-2.0 µg/mL ELISA Standard : Neutralization: Measured by its ability to neutralize CXCL8/IL‑8-induced chemotaxis in the BaF3 mouse pro‑B cell line transfected with human CXCR2. The Neutralization Dose (ND50) is typically 3-12 µg/mL in the presence of 10 ng/mL Recombinant Canine CXCL8/IL‑8. |

| 背景 | Interleukin 8 (IL-8), also named monocyte-derived neutrophil chemotactic factor (MDNCF), neutrophil-activating protein 1 (NAP-1), neutrophil-activating factor (NAF) and granulocyte chemotactic peptide (GCP), belongs to the Glu-Leu-Arg motif containing (ELR+) CXC chemokine family and has been designated CXCL8. IL-8 is a potent neutrophil chemoattractant that recruits neutrophils to sites of inflammation. IL-8 also activates neutrophil functions and through a poorly understood mechanism, promotes angiogenesis. The biological activites of IL-8 is mediated by two types of G protein-coupled chemokine receptors, CXCR1 and CXCR2. In normal tissues, IL-8 expression and secretion is barely detectable. Upon stimulation by a wide range of pro-inflammatory signals including exposure to IL-1, TNF, bacterial or viral products, IL-8 production is rapidly induced in many different cell types. Secreted IL-8 is not glycosylated but has N-terminal sequence heterogenecity due to proteolytic processing. In human, two major forms, the 72 amino acid (aa) monocyte-derived IL-8 and the 77 aa endothelial IL-8 have been identified. Whereas the 72 aa isoform is a more potent chemoattractant, only the 77 aa isoform can induce apoptosis in leukemic cells. The N-terminal pentapeptide in the 77 aa isoform has been identified as the active site for the IL-8 apoptotic activity. Canine IL-8 encodes a 101 aa precursor protein with a putative 22 aa signal peptide. It shares 77% and 87% aa sequence identity with human and porcine IL-8, respectively. Similar to human IL-8, recombinant canine IL-8 also undergoes N‑terminal processing. Two major peptides (the 79 aa and 74 aa variants that differ by an analogous N-terminal pentapeptide) are present in the recombinant canine IL-8 preparations. |

Chemotaxis Induced by CXCL8/IL‑8 and Neutralization by Canine CXCL8/IL‑8 Antibody. Recombinant Canine CXCL8/IL‑8 (Catalog # 1608-CL) chemoattracts the BaF3 mouse pro‑B cell line transfected with human CXCR2 in a dose-dependent manner (orange line). The amount of cells that migrated through to the lower chemotaxis chamber was measured by Resazurin (Catalog # AR002). Chemotaxis elicited by Recombinant Canine CXCL8/IL‑8 (10 ng/mL) is neutralized (green line) by increasing concentrations of Canine CXCL8/IL‑8 Monoclonal Antibody (Catalog # MAB16081). The ND50 is typically 3-12 µg/mL. |
