Recombinant Mouse CXCL1/KC (Catalog # 453-KC) chemoattracts the BaF3 mouse pro‑B cell line transfected with human CXCR2 in a dose-dependent manner (orange line). The amount of cells that migrated through to the lower chemotaxis chamber was measured by Resazurin (Catalog # AR002). Chemotaxis elicited by Recombinant Mouse CXCL1/KC (30 ng/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Mouse CXCL1/KC Antigen Affinity-purified Polyclonal Antibody (Catalog # AF-453-NA). The ND50 is typically 0.3‑1.5 µg/mL.
