IL-8 /77

Recombinant Human IL-8 (3-79) produced in E. coli is a single, non-glycosylated polypeptide chain containing 77 amino acids and having a molecular mass of 8904 Dalton.

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.

Lyophilized from a concentrated (1mg/ml) solution containing 20mM PBS pH-7.4 and 50mM sodium chloride.

rHuIL-8 /77 is fully biologically active when compared to standard. The ED50 as determined by its chemotaxis of hCXCR-2 transfected mouse BaF/3 cells is less than 2 ng/ml, corresponding to a Specific Activity of 5.0 x 10⁵ IU/ mg.

Less than 0.1ng/ug (1 IEU/ug) determined by LAL test.

It is recommended to reconstitute the lyophilized rHuIL-8 /77 in sterile 18MΩ-cm H₂O not less than 100ug/ml, which can then be further diluted to other aqueous solutions.

Lyophilized rHuIL-8 /77 although stable at room temperature for 3 weeks, should be stored desiccated below -18^oC. Upon reconstitution rHuIL-8 /77 should be stored at 4^oC between 2-7 days and for future use below -18^oC. For long-term storage it is recommended to add a carrier protein (0.1% HSA or BSA). Aliquot to avoid repeated freeze-thaw cycles.
