Detects mouse CCL7/MCP-3/MARC in direct ELISAs and Western blots. In direct ELISAs, approximately 15% cross‑reactivity with recombinant human Eotaxin and recombinant mouse (rm) JE is observed and less than 5% cross-reactivity with rmMCP-5 is observed.
Polyclonal Goat IgG
E. coli-derived recombinant mouse CCL7/MCP-3/MARC Gln24-Pro97 Accession # Q03366
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 CCL7/MCP‑3/MARC-induced chemotaxis in the BaF3 mouse pro‑B cell line transfected with human CCR2A. The Neutralization Dose (ND50) is typically 7.5-45 µg/mL in the presence of 2 µg/mL Recombinant Mouse CCL7/MCP‑3/MARC.
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 CCL7/MARC and Neutralization by Mouse CCL7/MARC Antibody.
Recombinant Mouse CCL7/ MARC (Catalog # 456-MC) 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 CCL7/ MARC (2 µg/mL) is neutralized (green line) by increasing concentrations of Mouse CCL7/MARC Antigen Affinity-purified Polyclonal Antibody (Catalog # AF-456-NA). The ND50 is typically 7.5-45 µg/mL.

Mouse MARC, a member of the beta subfamily of chemokines, was initially identified as a transcript that is induced in a mouse mast cell line after Fc epsilon RI triggering by IgE plus antigen. Sequence comparisons suggest that MARC may be the mouse homologue of the human MCP-3 gene. Mouse MARC/MCP-3 expression has also been detected during murine experimental allergic encephalomyelitis in the spinal cord, and in LPS-stimulated murine WEHI -3 cells and Swiss 3T3 cells where MARC expression is glucocorticoid-attenuated. Except for one amino acid subsititution, mouse MARC is identical to mouse FIC, the product of a growth factor‑activated gene. The mouse MARC cDNA encodes a 97 amino acid residue precursor protein with a 23 amino acid residue signal peptide that is cleaved to yield a 74 amino acid residue mature protein. Mouse CCR2, a mouse chemokine receptor, has been shown to bind JE/MCP-1 with high affinity and MARC/MCP-3 with lower affinity. The E. coli-expressed mouse MARC/MCP-3 produced at R&D Systems has been shown to be a monocyte and T-lymphocyte chemoattractant.
