Recombinant Mouse Chemerin chemo-attracts the BaF3 mouse pro-B cell line transfected with human Chem R23 in a dose-dependent manner (orange line). The amount of cells that migrated through to the lower chemotaxis chamber was measured by Resazurin. Chemotaxis elicited by Recombinant Mouse Chemerin (100ng/mL) is neutralized (green line) by increasing concentrations of C3890. The ND50 is typically 1-5ug/mL.
