Detects human CCL8/MCP‑2 in direct ELISAs and Western blots. In direct ELISAs and Western blots, less than 2% cross-reactivity with recombinant human (rh) MCP-1 and rhMCP-3 is observed. Neutralizes the biological activity of recombinant human MCP-2, but will not neutralize the biological activity of MCP-1 or MCP-3.
Polyclonal Goat IgG
Protein A or G purified
E. coli-derived recombinant human CCL8/MCP-2 Gln24-Pro99 Accession # P80075
Lyophilized from a 0.2 μm filtered solution in PBS with Trehalose.
<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 human monocytes. The Neutralization Dose (ND50) is typically 60-120 µg/mL in the presence of 0.4 µg/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 human monocytes in a dose-dependent manner (orange line). The amount of cells that migrated through the filter was measured by LeukoStat™ staining (Fisher Scientific). Chemotaxis elicited by Recombinant Human CCL8/MCP‑2 (0.4 µg/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Human CCL8/MCP‑2 Polyclonal Antibody (Catalog # AB-281-NA). The ND50 is typically 60‑120 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.
