|Synonyms||Epithelial Neutrophil Activating Peptide-78, CXCL5,ENA-78|
|Description||Epithelial cellderived neutrophilactivating peptide (ENA78) also known as C-X-C motif chemokine 5(CXCL5), is a small cytokine belonging to the CXC chemokine family. It is produced following stimulation of cells with the inflammatory cytokines interleukin-1 or tumor necrosis factor-alpha. Expression of CXCL5 has also been observed in eosinophils, and can be inhibited with the type II interferon, IFN-γ. This chemokine stimulates the chemotaxis of neutrophils possessing angiogenic properties Full length CXCL5 (78 a.a.) is cleaved at the Nterminal end by cathepsin G and chymotrypsin to ENA-74 (74 a.a.) and ENA-70 (70a.a.), with the shortened forms showing increased potency relative to full length CXCL5. CXCL5can signal through the CXCR2 receptor.
Recombinant human ENA-78/CXCL5 (9-78a.a.) produced in E.coli is a single non-glycosylated polypeptide chain containing 70 amino acids. A fully biologically active molecule, rhENA-78/CXCL5 (9-78a.a.) has a molecular mass of 7.7 kDa analyzed by reducing SDS-PAGE and is obtained by chromatographic techniques at GenScript.
|Biological Activity||The EC50 value of human ENA78/CXCL5 (9-78 a.a.) on Ca2+ mobilization assay in CHO-K1/G15/hCXCR2 cells (human G15 and human CXCR2 stably expressed in CHO-K1 cells) is less than 50 ng/ml.|
