Purity ~95% (SDS-PAGE). Eotaxin belongs to the platelet factor-4 family of chemokines. The gene symbol is SCYA11. The factor is being referred to also as Eotaxin-1 and has been renamed CCL11. Eotaxin induces substantial accumulation of eosinophils in the skin without significantly affecting the accumulation of neutrophils. Eotaxin is a potent stimulator of both guinea pig and human eosinophils in vitro. The Eotaxin receptor is a G-protein-coupled receptor selectively expressed in human eosinophils. Source: Recombinant protein corresponding to mouse Eotaxin-2 expressed in E. coli. Molecular Weight: ~12kD Biological Activity: Determined by the ability to induce chemotaxis of mouse lymphocytes at concentrations ranging between 10-100ng/mL. Endotoxin: <1EU/ug (LAL)
