Recombinant Mouse CCL24/Eotaxin-2/MPIF-2 (aa 24-119) Protein (Catalog #
Measured by its ability to neutralize CCL24/Eotaxin‑2/MPIF‑2-induced chemotaxis in the BaF3 mouse pro‑B cell line transfected with mouse CCR3. The Neutralization Dose (ND50) is typically 0.06-0.3 µg/mL in the presence of 20 ng/mL Recombinant Mouse CCL24/Eotaxin‑2/MPIF‑2.
Please Note: Optimal dilutions should be determined by each laboratory for each application.

Chemotaxis Induced by CCL24/Eotaxin‑2 and Neutralization by Mouse CCL24/ Eotaxin‑2 Antibody.
Recombinant Mouse CCL24/ Eotaxin‑2 (Catalog # 1017-MP) chemoattracts the BaF3 mouse pro‑B cell line transfected with mouse CCR3 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 Mouse CCL24/Eotaxin‑2 (20 ng/mL) is neutralized (green line) by increasing concentrations of Rat Anti-Mouse CCL24/Eotaxin‑2 Monoclonal Antibody (Catalog # MAB528). The ND50 is typically 0.06‑0.3 µg/mL.

Eotaxin-2, also named myeloid progenitor inhibitory factor (MPIF-2), is a member of the CC chemokine subfamily and is designated CCL24. Eotaxin-2 is constitutively expressed in the jejunum and spleen. It can also be induced in the lung by allergen challenge and IL-4. LPS and IL-4 also differentially regulate the expression of Eotaxin-2 in monocytes and macrophages. Mouse Eotaxin-2 cDNA encodes a 119 amino acid (aa) precursor protein that shares approximately 58% aa sequence identity with human Eotaxin-2. Functionally, Eotaxin-2 is most closely related to CCL11/Eotaxin and CCL26/Eotaxin-3. The three proteins share low sequence homology but have been shown to be potent eosinophil chemoattractants that bind and activate the chemokine receptor CCR3, a receptor that is highly expressed in eosinophils. Eotaxin-2 also has the ability to suppress myeloid cell proliferation, a biological function not shared by Eotaxin.
