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. RANDOX recombinant IL-8 comprises the 77 amino acid fragment (23-99) corresponding to the mature IL-8 protein and is expressed in E. coli with an amino-terminal hexahistidine tag.
