Purity ≥ 98% by SDS-PAGE and HPLC analyses. Endotoxin: ≤ 0.1ng/ug. Murine Eotaxin shares many of the biological and physical characteristics of Human Eotaxin. This chemokine exhibits a high chemotactic selectivity for eosinophils and belongs to the b-chemokine family (C-C) of cytokines, along with chemokines such as RANTES, MCP-3, and MIP-1alpha, Murine eotaxin is an 8.4kD protein containing 74 amino acid residues. Biological Activity: Recombinant Murine Eotaxin is fully biologically active compared to standard. Murine Eotaxin was found to induce chemotaxis of purified eosinophils at concentrations ranging between 100-1000ng/ml. Responding Cells (partial list): Eosinophils Concentration Range for most in vitro applications: 100-1000 ng/ml
