Interleukin-8 or CXCL8 (IL-8) is a proinflammatory chemokine that belongs to the C-X-C family. Monocytes and macrophages are the primary sources of IL-8 but it is also secreted by most nucleated cells. IL-8 binds to two G protein-coupled receptors, CXCR1 and CXCR2 and leads to the downstream activation of PI3K, MAPK, PKC, STAT3 and FAK pathways. IL-8 is responsible for the recruitment monocytes and neutrophils that results in a prolonged acute inflammation. The expression of IL-8 is influenced by inflammatory signals, chemical and environmental stress and hormones. Deregulation of IL-8 signaling has been observed in atherosclerosis, cardiovascular disease and solid tumors of bladder, prostate, ovary, glial cells and pancreas. Monoclonal Anti-Interleukin-8 antibody recognizes human IL-8. By immunoblotting, the antibody shows 100% cross reactivity with recombinant porcine IL-8, and no cross reactivity with recombinant rat CINC-2α.
Immunogen
purified, E. coli-derived, recombinant human IL-8.
Application
Monoclonal Anti-Interleukin-8 antibody may be used for neutralization assays; ND50 is 0.08-0.4 μg/ml. The antibody may be used for immunoblotting at a working concentration of 1-2 μg/ml. For ELISA a working concentration of 0.5 μg/ml may be used. Antibody concentration of 25 μg/ml may be used for immunocytochemistry using stimulated human peripheral blood mononuclear cells. For flow cytometry, 10 μL of 25 μg/ml stock antibody solution may be used for 1-5 X 105 cells.
Physical form
Lyophilized from a 0.2 μm filtered solution in phosphate buffered saline containing carbohydrates.

Chemoattractants and chemokines, such as interleukin 8 (IL-8), are defined by their ability to induce directed cell migration of responsive cells. The signal transduction pathway(s) leading to cell migration remain ill defined. We demonstrate that phosphatidylinositol-3-kinase (PI3K) activity, as determined

The polypeptide chemokine Interleukin-8 (IL8) plays a crucial role in inflammatory processes in humans. IL8 is involved in chronic inflammatory lung diseases, rheumatoid arthritis, and cancer. Previous studies have shown that the interaction of IL8 with its natural receptors CXCR1

The role of inflammation in airway epithelial cells and its regulation are important in several respiratory diseases. When disease is present, the barrier between the pulmonary circulation and the airway epithelium is damaged, allowing serum proteins to enter the airways.

Interleukin-8 (IL-8), the prototypic member of the CXC subfamily of chemokines, induces in neutrophils chemotaxis, the respiratory burst, granule release, and increased cell adhesion. The IL-8 receptor is a seven-transmembrane spanning receptor coupled to specific heterotrimeric G proteins including Gi
