Protein A or G purified from hybridoma culture supernatant
E. coli-derived recombinant mouse CCL12/MCP‑5 Gly23-Gly104 Accession # Q62401
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose. *Small pack size (SP) is supplied as a 0.2 µm filtered solution in PBS.
<0.10 EU per 1 μg of the antibody by the LAL method.
Measured by its ability to neutralize CCL12/MCP‑5-induced chemotaxis in the BaF3 mouse pro‑B cell line transfected with human CCR2A. The Neutralization Dose (ND50) is typically 0.5-2.5 µg/mL in the presence of 0.2 µg/mL Recombinant Mouse CCL12/MCP‑5.
Please Note: Optimal dilutions should be determined by each laboratory for each application. General Protocols are available in the Technical Information section on our website.
Chemotaxis Induced by CCL12/MCP‑5 and Neutralization by Mouse CCL12/ MCP‑5 Antibody.
Recombinant Mouse CCL12/MCP‑5 (Catalog # 428‑P5) chemoattracts the BaF3 mouse pro‑B cell line transfected with human CCR2A 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 CCL12/MCP‑5 (0.2 µg/mL) is neutralized (green line) by increasing concentrations of Rat Anti-Mouse CCL12/MCP‑5 Monoclonal Antibody (Catalog # MAB4281). The ND50 is typically 0.5-2.5 µg/mL.
Preparation and Storage

6 months, -20 to -70 °C under sterile conditions after reconstitution.
CCL12, also called MCP-5, is expressed constitutively in the thymus and lymph nodes. Under inflammatory conditions, CCL12 expression is also induced in activated macrophages and mast cells. Mouse CCL12 encodes a 104 amino acid (aa) precursor protein with a 22 aa signal sequence that is cleaved to generate a 82 aa mature protein. Recombinant CCL12 is a potent chemoattractant for monocytes and lymphocytes but not neutrophils. CCL12 has been found to be a functional ligand for CCR2.
