STORAGE:  2-8 C in the dark.

IMPORTANT: Sodium azide forms explosive compounds with heavy metals. These products contain <0.05% (w/w) azide which with repeated contact with lead and copper commonly found in plumbing drains may result in the buildup of shock sensitive compounds. Dispose in accordance with regulations from your institute.

Description:

C-X-C motif chemokine 5 (CXCL5), or ENA-78, is a small cytokine belonging to the CXC chemokine family that is also known as epithelial-derived neutrophil-activating peptide 78 (ENA-78) and LIX (Liposaccharide-Induced CXC chemokine). 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. CXCL5 has been implicated in connective tissue remodeling. CXCL5 has been also described to regulate neutrophil homeostasis. CXCL5 is well known to have chemotactic and activating functions on neutrophil, mainly during acute inflammatory responses. However CXCL5 expression is also higher in atherosclerosis (a chronic inflammatory condition) but is not associated with neutrophil infiltration. CXCL5 has a protective role in atherosclerosis by directly controlling macrophage foam cell formation.
