Human Interleukin-8 (hIL-8) Recombinant Protein #94853
Product Information
Storage
Recombinant human IL-8 is supplied as lyophilized material that is very stable at -20°C. It is recommended to reconstitute with sterile water at a concentration of 0.1 mg/mL, which can be further diluted in aqueous solutions as needed. Addition of a carrier protein (0.1% HSA or BSA) is recommended for long term storage.
Once in solution, store at 4°C and use within 1 month, or store at -20ºC to -80ºC and use within 3 months to prevent loss of potency. Aliquot to avoid multiple freeze/thaw cycles if storing reconstituted material at -20ºC to -80ºC.

Background
The prototypical CXC chemokine, IL-8, is best known for effects on neutrophils, specifically its ability to act as a chemoattractant and activate degranulation and respiratory burst (1,2,3).
IL-8 is produced by a number of cell types, including monocytes, T cells, neutrophils, fibroblasts, endothelial cells, and others (1). In addition to its effects on neutrophils, IL-8 promotes angiogenesis, inhibits endothelial cell apoptosis, and promotes the proliferation of melanoma cells in an autocrine fashion (1). As a result, IL-8 may be a contributing factor to the development of certain cancers (1,2). There are two distinct receptors for IL-8, CXCR1 and CXCR2; both are G protein-coupled receptors (1). Ligand binding induces Ca2+ mobilization and activates the PI3K, PKC, Rho, and Rac pathways (1,3).
