Anti-IL-8 antibodies enable researchers to detect and measure the IL-8 antigen in biological samples. This target is a reported synonym of the CXCL8 gene, which encodes C-X-C motif chemokine ligand 8. This protein is known to function in angiogenesis and the cellular response to lipopolysaccharides, among other biological roles. The human version of IL-8 has a canonical amino acid length of 99 residues and a protein mass of 11.1 kilodaltons. It is reported to be a secreted protein that is notably expressed in the tonsil, testis, stomach, lymph node, and kidney. Other names for this target antigen include GCP-1 and GCP1. Over 750 citations in the literature describe the use of IL-8 antibodies in research. ELISA, Western Blot, and Immunohistochemistry are common applications for these antibodies.
