Description

CXCL5 (ENA-78) is a potent CXC chemokine that drives neutrophil recruitment through CXCR2 signaling, making it central to studies of acute inflammation and tumor-associated immune infiltration. This tag-free recombinant human CXCL5, spanning residues 41–114 of the mature processed sequence, demonstrates robust chemotactic activity on human peripheral blood neutrophils at 5.0–10 ng/mL, providing a suitable basis for neutrophil migration assays, CXCR2-dependent MAPK and NF-κB signaling studies, and in vivo inflammation models. Endotoxin levels below 1.0 EU/μg minimize LPS-driven artifacts that can confound innate immune cell readouts, while purity exceeding 97% by SDS-PAGE supports use as a reliable reference standard in CXCL5 detection ELISAs or as a positive control for antibody validation in western blot. The E. coli-derived, untagged format faithfully represents the native mature chemokine, aligning with standards expected in functional bioassays where receptor-binding fidelity is essential.

Target Background

Function

Involved in neutrophil activation. In vitro, ENA-78(8-78) and ENA-78(9-78) show a threefold higher chemotactic activity for neutrophil granulocytes.
