Recombinant Mouse Eotaxin-2

Eotaxin-2 is a CC chemokine that is a specific agonist for the chemokine receptor CCR3. It is produced by activated monocytes and T lymphocytes. Eotaxin-2 induces chemotaxis of eosinophils as well as basophils and the release of histamine and leukotriene C4 from basophils. Eotaxin-2 has the same efficacy as eotaxin, but is somewhat less potent. ¹
Additionally, Eotaxin-2 inhibits the proliferation of multipotential hematopoietic progenitor cells.

The biological activity of Mouse Eotaxin-2 was determined by its ability to induce chemotaxis of mouse BaF/3 cells transfected with mCCR3. The expected ED₅₀= 150 - 600 ng/ml.
