|Names||Interleukin-8, IL-8, C-X-C Motif Chemokine 8, Emoctakin, Granulocyte Chemotactic Protein 1, GCP-1, Monocyte-Derived Neutrophil Chemotactic Factor, MDNCF, Monocyte-Derived Neutrophil-Activating Peptide, MONAP, Neutrophil-Activating Protein 1, NAP-1, Protei|
|Formulation||Lyophilized from a 0.2 ?M filtered solution of 20mM PB, 150mM NaCl, pH 7.4|
|Shipping||The product is shipped at ambient temperature.|
|Reconstitution||Always centrifuge tubes before opening. Do not mix by vortex or pipetting.|
It is not recommended to reconstitute to a concentration less than 100 ?g/ml.
Dissolve the lyophilized protein in 1X PBS.
Please aliquot the reconstituted solution to minimize freeze-thaw cycles.
|Storage||Lyophilized protein should be stored at < -20°C, though stable at room temperature for 3 weeks.|
Reconstituted protein solution can be stored at 4-7°C for 2-7 days.
Aliquots of reconstituted samples are stable at < -20°C for 3 months.
|Biological Activity||Recombinant IL-8 (3-79) is fully biologically active when compared to standards.|
ED50 is less than 2 ng/ml as determined by its chemotaxis of hCXCR-2 transfected mouse BaF/3 cells.
Specific Activity of 5.0 x 105 IU/mg.
|Purity||Greater than 95% as determined by RP-HPLC and reducing SDS-PAGE.|
|Endotoxin||Less than 0.1 ng/?g (1 IEU/?g).|
|Amino Acid Sequence|
|Background||Interleukin-8 (IL-8) belongs to the neutrophil-specific CXC family of chemokines. It is one of the initial cytokines released from a variety of cell types, including T cells, endothelial cells and fibroblasts, in response to an inflammatory stimulus and acts by recruiting neutrophils, T-cells and basophils to the site of inflammation. Elevated Interleukin-8 levels are associated with the onset of a variety of disease states.|
