CCL26 (eotaxin-3) is a potent CCR3 agonist central to eosinophil recruitment in allergic inflammation, making validated chemotactic activity essential for meaningful in vitro and in vivo studies. This tag-free recombinant human CCL26, encompassing the full-length mature sequence (residues 24–94), drives directional migration of CCR3-transfected HEK293 cells at 0.5–2.0 μg/ml in chemotaxis bioassays, confirming robust signaling through its cognate receptor. Endotoxin levels below 1.0 EU/μg minimize LPS-driven artifacts in sensitive immune cell assays, which supports use in eosinophil and basophil migration studies, CCR3-dependent MAPK and calcium flux signaling experiments, and in vivo models of airway or allergic inflammation. Purity exceeding 97% by SDS-PAGE, combined with this stringent endotoxin control, also provides a suitable basis for deployment as a reference standard in chemokine detection assays or as a positive control antigen in ELISA and antibody validation workflows.
