Discription：CXCL5 is a small cytokine also known as epithelial-derived neutrophil-activating peptide 78 （ENA-78） . The protein is produced following stimulation of cells with the inflammatory cytokine interleukin-1 or tumor necrosis factor-alpha. In vitro, ENA-78 （8-78） and ENA-78 （9-78） show a threefold higher chemotactic activity for neutrophil granulocytes. They are produced by proteolytic cleavage after secretion from peripheral blood monocytes. Recombinant human CXCL5 （5-78 a.a.） contains 74 amino acids and it is a single non-glycosylated polypeptide chain. Human CXCL5 shares 57％ amino acid sequence identity with mouse and rat CXCL5. Recombinant Human ENA-78/CXCL5 is an 8.1kDa protein containing 74 amino acid residues.
