别名 | CCL2; MCAF; MCP-1 |
反应种属 | Human |
应用 | Western Blot,Neutralization |
目标/特异性 | Detects human CCL2/JE/MCP-1 in direct ELISAs and Western blots. In direct ELISAs, approximately 20% cross-reactivity with recombinant canine MCP-1 is observed and less than 5% cross-reactivity with recombinant mouse MCP-1, recombinant rat MCP-1, recombinant human (rh) Eotaxin, rhMCP-2 and rhMCP-4 is observed. |
使用方法 | Western Blot: 0.1 µg/mL Neutralization: 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 1.5-4.5 µg/mL in the presence of 150 ng/mL Recombinant Human CCL2/JE/MCP‑1. |

背景 | CCL2, also known as monocyte chemotactic and activating factor (MCAF), was initially purified independently by two groups based on its ability to chemoattract monocytes. The human CCL2 cDNA encodes a 99 amino acid residue precursor protein with a 23 residue hydrophobic signal peptide that is cleaved to generate the 76 residue mature protein. Natural CCL2 is heterogeneous in size due to the addition of O-linked carbohydrates and sialic acid residues. In addition to fibroblasts; tumor cells, smooth muscle cells, endothelial cells, and mononuclear phagocytes can also produce CCL2 either constitutively or upon stimulation by various stimuli. CCL2 is a member of the beta (C-C) subfamily of chemokines. The existence of MCP-2 and MCP-3 with 62% and 73% amino acid identity respectively, to CCL2 have been reported. Consistent with it being a member of the chemokine beta family, CCL2 has been shown to chemoattract monocytes. In addition, it will also activate monocytes to be cytostatic for some human tumor cell lines; to increase cytosolic free calcium; to generate and release monocyte superoxide anions and to release monocyte lysosomal enzymes in vitro. CCL2 was reported to be capable of regulating adhesion molecule expression and cytokine production in human monocytes as well as chemoattracting, activating, and inducing histamine release from basophils. The biological roles played by CCL2 in a number of inflammatory and non-inflammatory disease states characterized by the accumulation of leukocytes at the site of the lesion, including atherosclerosis, delayed hypersensitivity reactions, etc., are being determined. CCL2 can bind to the C-C chemokine receptor-1 that also binds MIP-1 alpha, RANTES and MIP-1 beta. A specific receptor for CCL2 has also been cloned from THP-1 and MonoMac 6 cells. |

Detection of Recombinant Human CCL2/JE/MCP‑1 by Western Blot. Western blot shows 25 ng of Recombinant Human CCL2/JE/MCP‑1 (Catalog # 279‑MC), Recombinant Mouse CCL2/JE/MCP‑1 (Catalog # 479-JE), Recombinant Rat CCL2/JE/MCP‑1 (Catalog # 3144-JE), Recombinant Human CCL7/MCP‑3/MARC (Catalog # 282-P3), Recombinant Human CCL11/Eotaxin (Catalog # 320-EO), Recombinant Human CCL8/MCP‑2 (Catalog # 281-CP), and Recombinant Human CCL13/MCP‑4 (Catalog # 327-P4). PVDF Membrane was probed with 0.1 µg/mL of Goat Anti-Human CCL2/JE/MCP‑1 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF-279-NA) followed by HRP-conjugated Anti-Goat IgG Secondary Antibody (Catalog # HAF109). A specific band was detected for CCL2/JE/MCP‑1 at approximately 12 kDa (as indicated). This experiment was conducted under reducing conditions and using Immunoblot Buffer Group 3. |
