CXCL5, also known as neutrophil activating peptide 78 (ENA‐78), is a CXC chemokine containing ELR motif. CXCL5 promotes angiogenesis through interaction with its specific receptor CXCR2. CXCL5 is expressed by many immune cells, such as macrophages, eosinophils, and non-immune cells including mesothelial cells, and fibroblasts.CXCL5/CXCR2 axis not only contributes to the recruitment of neutrophils but also regulates the function of neutrophils in melanoma[1][2]. ENA-78/CXCL5 Protein, Human (HEK293) is produced in HEK293 cells, and consists of 78 amino acids (A37-N114) .
