Monoclonal Rat IgG2B Clone # 123616
Protein A or G purified from hybridoma culture supernatant
E. coli-derived recombinant mouse CCL2/JE/MCP-1 Gln24-Arg96 Accession # P10148
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 CCL2/JE/MCP‑1-induced chemotaxis in the BaF3 mouse pro‑B cell line transfected with human CCR2A. The Neutralization Dose (ND50) is typically 0.75-3.0 µg/mL in the presence of 40 ng/mL Recombinant Mouse CCL2/JE/MCP‑1.
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 CCL2/JE and Neutralization by Mouse CCL2/JE Antibody. Recombinant Mouse CCL2/JE (Catalog # 479-JE) 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 CCL2/JE (40 ng/mL) is neutralized (green line) by increasing concentrations of Mouse CCL2/JE Monoclonal Antibody (Catalog # MAB479). The ND50 is typically 0.75-3.0 µg/mL.

Mouse CCL2 is a member of the beta (C-C) subfamily of chemokines. The mouse CCL2 gene was initially identified as a platelet-derived growth factor-inducible gene in mouse fibroblasts. Mouse CCL2 cDNA encodes a 148 amino acid (aa) residue with a putative 23 aa signal peptide that is cleaved to generate the mature protein. Mouse CCL2 shares 82% amino acid sequence identity with rat CCL2. Mouse CCL2 also shares 55% amino acid sequence identity with human MCP-1. Compared to human MCP-1, mouse CCL2 has a 49 aa residue extension at the carboxy-terminus. When a DNA sequence encoding the 125 aa residue of the mature CCL2 protein was expressed in E. coli at R&D Systems, the purified protein had the predicted N-terminus but a mass of 8525 Da. The truncation of most of the C-terminal extension could be due either to purification artifact or to post-translational modification. The truncated recombinant CCL2 has a potency similar to that of human MCP-1 in the monocyte chemotaxis assay. Mouse CCL2 has full activity on human cells while human MCP-1 has limited activity on mouse cells.
