CXCL2 (GRO-β) is a potent neutrophil chemoattractant that signals through CXCR2 to drive inflammatory cell recruitment, and this recombinant form demonstrates confirmed chemotactic activity on human CXCR2-transfected HEK293 cells at 10–100 ng/mL, providing a reliable positive control for migration and chemotaxis assays. The tag-free protein encompasses the complete mature sequence (residues 35–107), preserving native receptor-binding topology critical for accurate CXCR2-mediated MAPK and NF-κB signaling studies. Endotoxin levels below 1.0 EU/μg minimize LPS-driven artifacts in sensitive immune cell experiments, making this preparation appropriate for in vivo neutrophil recruitment models, antibody development workflows including ELISA standard curves, and functional assays where chemokine-specific effects must be distinguished from endotoxin contamination. Purity exceeding 97% by SDS-PAGE, combined with this stringent endotoxin control, satisfies the quality thresholds commonly required for use as a reference standard in cytokine detection assays.
