| 反应种属 | Human |
| 应用 | Western Blot(0.1 µg/mL) |
| 目标/特异性 | Detects human CXCL11/I-TAC in direct ELISAs and Western blots. In direct ELISAs, less than 5% cross-reactivity with recombinant mouse I-TAC is observed. |
| 使用方法 | Western Blot: 0.1 µg/mL Neutralization: Measured by its ability to neutralize CXCL11/I‑TAC-induced chemotaxis in the BaF3 mouse pro‑B cell line transfected with human CXCR3. The Neutralization Dose (ND50) is typically 0.5-1.5 µg/mL in the presence of 0.05 µg/mL Recombinant Human CXCL11/I‑TAC. |

| R&D Systems personnel manually curate a database that contains references using R&D Systems products. The data collected includes not only links to publications in PubMed, but also provides information about sample types, species, and experimental conditions. Villitis of unknown etiology is associated with a distinct pattern of chemokine up-regulation in the feto-maternal and placental compartments: implications for conjoint maternal allograft rejection and maternal anti-fetal graft-versus-host disease. | |

| 背景 | CXCL11, also known as I-TAC, SCYB9B, H174 and beta -R1, is a non-ELR CXC chemokine. CXCL11 cDNA encodes a 94 amino acid (aa) residue precursor protein with a 21 aa residue putative signal sequence, which is cleaved to form the mature 73 aa residue protein. CXCL11 shares 36% and 37% amino acid sequence homology with IP-10 and MIG (two other known human non-ELR CXC chemokines), respectively. CXCL11 is expressed at low levels in normal tissues including thymus, spleen and pancreas. The expression of CXCL11 mRNA is radically up regulated in IFN-gamma and IL-1 stimulated astrocytes. Moderate increase in expression is also observed in stimulated monocytes. CXCL11 has potent chemoattractant activity for IL-2 activated T cells and transfected cell lines expressing CXCR3, but not freshly isolated T cells, neutrophils, or monocytes. The gene encoding CXCL11 has been mapped to chromosome 4. |

Chemotaxis Induced by CXCL11/I‑TAC and Neutralization by Human CXCL11/I‑TAC Antibody. Recombinant HumanCXCL11/I‑TAC (Catalog # 672-IT) chemoattracts the BaF3 mouse pro‑B cell line transfected with human CXCR3 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 CXCL11/I‑TAC (0.05 µg/mL) is neutralized (green line) by increasing concentrations of Goat Anti-Human CXCL11/I-TAC Antigen Affinity-purified Polyclonal Antibody (Catalog # AF260). The ND50 is typically 0.5-1.5 µg/mL. |
