  • 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.
Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.
Data Examples
Immunocytochemistry
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).

Immunohistochemistry
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). The ND50 is typically
0.1‑0.5 µg/mL.

Background: IL-8/CXCL8

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 vivo and in vitro.
