Recombinant Cotton Rat CCL4/MIP‑1 beta (Catalog # 1024-MB) chemoattracts the BaF3 mouse pro‑B cell line transfected with mouse CCR5 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 Cotton Rat CCL4/MIP‑1 beta (10 ng/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Cotton Rat CCL4/MIP‑1 beta Antigen Affinity-purified Polyclonal Antibody (Catalog # AF1024). The ND50 is typically 0.15-0.6 µg/mL.
