ENA-78 (epithelial cell-derived neutrophil activating peptide-78) gene expression is associated with sepsis, atherosclerosis, COPD (chronic obstructive pulmonary disease), psoriasis and gastrointestinal inflammation. ENA-78 is angiogenic factor and is associated with cancer progression. Upregulation of ENA-78 gene is observed in non‐small‐cell lung cancer, head, neck, gastric, pancreatic, colorectal, prostate and lung cancer squamous cell carcinoma.

ENA-78 is a CXC chemokine that signals through the CXCR2 receptor. It is expressed in monocytes, platelets, endothelial cells, and mast cells. Recombinant human ENA-78 is a 7.8 kDa protein consisting of 71 amino acid residues.

General description

ENA-78 (epithelial cell-derived neutrophil activating peptide-78) is a CXC chemokine that signals through the CXCR2 receptor. It is expressed in monocytes, platelets, endothelial cells, and mast cells. ENA-78 is a chemoattractant for neutrophils. The murine homolog of ENA-78 is called LIX. Three N-terminal truncated variants of human ENA-78; ENA 5-78, ENA 8-78, ENA 9-78, contain 74, 71, and 70 amino acid residues, respectively, possess increased biological activity. ENA-78 contains the four conserved cysteine residues present in CXC chemokines, and also contains the ‘;ELR’; motif common to CXC chemokine that bind to the CXCR1 and CXCR2 receptors. Recombinant human ENA-78 is a 7.8 kDa protein consisting of 71 amino acid residues. The ENA-78 gene is mapped to human chromosome 4q13.3.

Physical form

Lyophilized with no additives.

Reconstitution

Centrifuge the vial prior to opening. Reconstitute in water to a concentration of 0.1-1.0 mg/ml. Do not vortex. This solution can be stored at 2-8°C for up to 1 week. For extended storage, it is recommended to further dilute in a buffer containing a carrier protein (example 0.1% BSA) and store in working aliquots at -20°C to -80°C.
