Description : Interleukin-8 (IL-8) is encoded by the IL8 gene andproduced by macrophages and other cell types such as epithelial cells. It is also synthesized by endothelial cells, which store IL-8 in their storage vesicles. There are many receptors capable to bind IL-8, the most affinity to IL-8 are receptors CXCR1, and CXCR2. As a member of the CXC chemokine family, function of IL-8 is the induction of chemotaxis in its target cells, like neutrophil granulocytes, basophils, and T-cells. IL-8 (72a.a.) has a 5-10-fold higher activity on neutrophil activation, compared to IL-8 (77a.a.). IL-8 is often associated with inflammation and has been cited as a proinflammatory mediator in gingivitis and psoriasis.
Source : E. coli
Species : Human
Form : Lyophilized from a 0.2 µm filtered concentrated solution in PBS, pH 7.4.
Bio-activity : Fully biologically active when compared to standard. The ED50 as determined by a chemotaxis bioassay using human CXCR2 transfected mouse BaF3 cells is less than 2 ng/ml, corresponding to a specific activity of > 5.0 × 10^5 IU/mg.
Molecular Mass : Approximately 8.4 kDa, a single non-glycosylated polypeptide chain containing 72 amino acids.
AA Sequence : SAKELRCQCIKTYSKPFHPKFIKEL RVIESGPHCANTEIIVKLSDGRELC LDPKENWVQRVVEKFLKRAENS
Endotoxin : Less than 1 EU/µg of rHuIL-8, 72a.a./CXCL8 as determined by LAL method.
Purity : > 97 % by SDS-PAGE and HPLC analyses.
Storage : This lyophilized preparation is stable at 2-8 centigrade, but should be kept at -20 centigrade for long term storage, preferably desiccated. Upon reconstitution, the preparation is stable for up to one week at 2-8 centigrade. For maximal stability, apportion the reconstituted preparation into working aliquots and store at -20 centigrade to -70 centigrade. Avoid repeated freeze/thaw cycles.
Reconstitution : Reconstitute in sterile distilled water or aqueous buffer containing 0.1 % BSA to a concentration of 0.1-1.0 mg/mL. Stock solutions should be apportioned into working aliquots and stored at ≤ -20 centigrade. Further dilutions should be made in appropriate buffered solutions.
Quality Statement : Our GMP proteins are produced according to relevant sections of the following documents: WHO TRS, No. 822, 1992 Annex 1, Good Manufacturing Practices for Biological Products; USP Chapter 1043, Ancillary Materials for Cell, Gene and Tissue-Engineered Products and USP Chapter 92, Growth Factors and Cytokines Used in Cell Therapy Manufacturing.

IL8 plays a role in regulating and promoting the migration and activation of inflammatory cells in the inflammatory response.

Which diseases can be treated with IL8? 12/02/2019

Can be used to treat inflammatory diseases (such as rheumatoid arthritis, psoriasis), tumors (such as lung cancer, breast cancer) and other diseases.

Is IL8 relevant to immunotherapy? 03/18/2019

Yes, IL8 is closely related to immunotherapy, which can enhance the role of the immune system and assist in the treatment of certain diseases.

By what method is IL8 generally prepared? 02/03/2019

IL8 is generally prepared by gene recombination technology, and the IL8 gene is introduced into the appropriate expression system, and then expressed and purified.
