应用 | Western Blot,Immunohistochemistry,Immunocytochemistry,Neutralization |
目标/特异性 | Detects human IL-8/CXCL8 in direct ELISAs and Western blots. In direct ELISAs, less than 1% cross-reactivity with recombinant canine IL-8/CXCL8, recombinant feline IL-8/CXCL8 and recombinant porcine IL-8/CXCL8 is observed. |
使用方法 | Western Blot: 0.1 µg/mL Immunohistochemistry: 5-15 µg/mL Immunocytochemistry: 5-15 µg/mL Neutralization: Measured by its ability to neutralize IL-8/CXCL8-induced chemotaxis in the BaF3 mouse pro‑B cell line transfected with human CXCR2. The Neutralization Dose (ND50) is typically 0.1-0.5 µg/mL in the presence of 20 ng/mL Recombinant Human IL-8/CXCL8. |

背景 | CXCL8 was originally discovered and purified independently by a number of laboratories as a neutrophil chemotactic and activating factor. It was also referred to as neutrophil chemotactic factor (NCF), neutrophil activating protein (NAP), monocyte-derived neutrophil chemotactic factor (MDNCF), T-lymphocyte chemotactic factor (TCF), granulocyte chemotactic protein (GCP) and leukocyte adhesion inhibitor (LAI). Many cell types, including monocyte/macrophages, T cells, neutrophils, fibroblasts, endothelial cells, keratinocytes, hepatocytes, chondrocytes, and various tumor cell lines, can produce CXCL8 in response to a wide variety of pro-inflammatory stimuli such as exposure to IL-1, TNF, LPS, and viruses. CXCL8 is a member of the alpha (CXC) subfamily of chemokines, which also includes platelet factor 4, GRO, IP-10, etc. CXCL8 is a potent chemoattractant for neutrophils. In addition, CXCL8 also has a wide range of other pro-inflammatory effects. CXCL8 causes degranulation of neutrophil specific granules and azurophilic granules. CXCL8 induces expression of the cell adhesion molecules CD11/CD18 and enhances the adherence of neutrophils to endothelial cells and sub-endothelial matrix proteins. Besides neutrophils, CXCL8 is also chemotactic for basophils, T cells and eosinophils. CXCL8 has been reported to be a co-mitogen for keratinocytes and was also shown to be an autocrine growth factor for melanoma cells. CXCL8 was also reported to be angiogenic both in vivoandin vitro. |

IL-8/CXCL8 in Human PBMCs. IL-8/CXCL8 was detected in immersion fixed human peripheral blood mononuclear cells (PBMCs) stimulated with PMA and ionomycin using 10 µg/mL Human IL-8/CXCL8 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF‑208‑NA) for 3 hours at room temperature. Cells were stained with the NorthernLights™ 557-conjugated Anti-Goat IgG Secondary Antibody (red; Catalog # NL001) and counterstained with DAPI (blue).

IL-8/CXCL8 in Human Tonsil. IL-8/CXCL8 was detected in immersion fixed paraffin-embedded sections of human tonsil (surgically removed due to severe EBV-induced mononucleosis) using Human IL-8/CXCL8 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF‑208‑NA) overnight at 4 °C. Tissue was stained (brown) and counterstained with hematoxylin (blue). View our protocol for Chromogenic IHC Staining of Paraffin-embedded Tissue Sections. | |
Chemotaxis Induced by IL-8/CXCL8 and Neutralization by Human IL-8/CXCL8 Antibody. Recombinant Human IL-8/CXCL8 (Catalog # 208-IL) 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 Human IL-8/CXCL8 (20 ng/mL) is neutralized (green line) by increasing concentrations of Human IL-8/CXCL8 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF-208-NA).
