Product Specs

Introduction
Chemokine (C-X-C motif) ligand 5 (CXCL5), also known as epithelial-derived neutrophil-activating peptide 78 (ENA-78), is a small cytokine belonging to the CXC chemokine family. Produced upon stimulation of cells by inflammatory cytokines interleukin-1 or tumor necrosis factor-alpha, CXCL5 is also expressed in eosinophils, with expression inhibitable by interferon-gamma. This chemokine, which stimulates neutrophil chemotaxis and exhibits angiogenic properties, exerts its effects by interacting with the CXCR2 chemokine receptor on the cell surface. The gene encoding CXCL5, located on human chromosome 4 among several other CXC chemokine genes, comprises four exons. CXCL5 has been implicated in the remodeling of connective tissue.
Description

Recombinant Human Epithelial Neutrophil-Activating Protein 78, produced in E. coli, is a single, non-glycosylated polypeptide chain consisting of 71 amino acids (8-78 a.a.). This protein has a molecular weight of 7.8 kDa. The CXCL5 is purified using proprietary chromatographic techniques.

Physical Appearance
Sterile Filtered White lyophilized powder.
Formulation
Lyophilized from a 0.2 µm filtered concentrated solution in 1xPBS, pH 7.4.
Solubility
Reconstitute the lyophilized ENA-78 in sterile 18 MΩ-cm H2O to a concentration of at least 100 µg/ml. This solution can be further diluted into other aqueous solutions.
Stability
Lyophilized ENA78 is stable at room temperature for 3 weeks but should be stored desiccated below -18°C. Upon reconstitution, CXCL5 should be stored at 4°C for 2-7 days. For long-term storage, freeze at -18°C. Adding a carrier protein (0.1% HSA or BSA) is recommended for long-term storage. Avoid repeated freeze-thaw cycles.
Purity
Greater than 97.0% as determined by:
(a) Reverse-Phase High-Performance Liquid Chromatography (RP-HPLC) analysis.
(b) SDS-PAGE analysis.
Biological Activity
Biological activity is assessed by the ability to induce chemotaxis of human peripheral blood neutrophils within a concentration range of 10.0-100.0 ng/ml.
Synonyms
Small inducible cytokine B5, CXCL5, Epithelial-derived neutrophil-activating protein 78, Neutrophil-activating peptide ENA-78, ENA-78(1-78), chemokine (C-X-C motif) ligand 5, SCYB5.

Product Science Overview

Structure and Production

CXCL5 is produced by various cell types, including epithelial cells, in response to inflammatory cytokines such as interleukin-1 (IL-1) and tumor necrosis factor-alpha (TNF-α) . The protein consists of 78 amino acids and has a molecular weight of approximately 8.3 kDa . The recombinant form of CXCL5, specifically the 8-78 amino acid sequence, is often used in research to study its biological functions and therapeutic potential.

Biological Functions

CXCL5 is primarily involved in the recruitment and activation of neutrophils, a type of white blood cell essential for the immune response. Upon binding to its receptor, CXCR2, on the surface of neutrophils, CXCL5 induces chemotaxis, guiding these cells to the site of infection or injury . This process is vital for the body’s defense against pathogens and the resolution of inflammation.

Clinical Significance

Research has shown that CXCL5 plays a significant role in various inflammatory diseases and conditions. For instance, elevated levels of CXCL5 have been observed in patients with acute coronary syndromes (ACS), suggesting its involvement in endothelial inflammation . Additionally, studies have indicated that genetic variations in the CXCL5 gene may influence the prognosis of ACS and the effectiveness of statin therapy .

Therapeutic Potential

Given its role in inflammation and immune response, CXCL5 is a potential target for therapeutic interventions. Modulating the activity of CXCL5 or its receptor, CXCR2, could provide new treatment options for inflammatory diseases, including cardiovascular diseases and chronic inflammatory conditions .
