Detects human CCL8/MCP‑2 in direct ELISAs and Western blots. In direct ELISAs and Western blots (non-reducing conditions), less than 40% cross‑reactivity with recombinant human (rh) HCC-1 is observed, less than 10% cross‑reactivity with rhEotaxin is observed, and less than 5% cross‑reactivity with rhMCP-1 is observed. Neutralizes the biological activity of rhCCL8. This antibody will not neutralize the biological activity of rhMCP-1, recombinant mouse JE, or rhMCP-3.
Polyclonal Goat IgG
E. coli-derived recombinant human CCL8/MCP-2 Gln24-Pro99 Accession # P80075
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 CCL8/MCP‑2-induced chemotaxis in the BaF3 mouse pro‑B cell line transfected with human CCR5. The Neutralization Dose (ND50) is typically 1.5-5.0 µg/mL in the presence of 250 ng/mL Recombinant Human CCL8/MCP‑2.
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 CCL8/MCP‑2 and Neutralization by Human CCL8/MCP‑2 Antibody.
Recombinant Human CCL8/MCP‑2 (Catalog # 281‑CP) chemoattracts the BaF3 mouse pro‑B cell line transfected with human CCR5 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 Human CCL8/ MCP‑2 (250 ng/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Human CCL8/MCP‑2 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF-281-NA). The ND50 is typically 1.5-5.0 µg/mL.

MCP-2 and MCP-3 are two monocyte chemotactic proteins produced by human MG-63 osteosarcoma cells. Both MCP-2 and MCP-3 are members of the C-C family of chemokines and share 62% and 71% amino acid sequence identity, respectively, with MCP-1. MCP-3 also shares 58% amino acid identity with MCP-2.
Similar to other C-C chemokines, all three MCP proteins are monocyte chemoattractants. In addition, the three MCPs can chemoattract activated NK cells as well as CD4+ and CD8+ T lymphocytes. All three cytokines have also been shown to attract eosinophils and induce histamine secretion from basophils.
