人中性粒細胞激活肽|Human ENA-78 (8-78)

Synonyms :

Epithelial Neutrophil Activating Peptide-78, CXCL5

Description :

ENA-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.

Stability :

The lyophilized protein is stable for at least 2 years from date of receipt at -20⁰C. Reconstituted ENA-78 is stable for at least 3 months when stored in working aliquots with a carrier protein at -20⁰C. Avoid repeated freeze/thaw cycles.

Purity :

Greater than 98% by SDS-PAGE gel and HPLC analyses.

Endotoxin Level :

Endotoxin level is less than 0.1 ng per μg (1EU/μg).

Biological Activity :

Determined by its ability to chemoattract human neutrophils using a concentration range of 10.0-100.0 ng/ml.
