Scientific Data Images for Human CXCL11/I-TAC Antibody
Chemotaxis Induced by CXCL11/I‑TAC and Neutralization by Human CXCL11/I‑TAC Antibody.
Recombinant Human CXCL11/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.
Detection of Human CXCL11/I-TAC by Block/Neutralize
CXCR7-mediated Rb degradation requires ligand.pLEC cultures were infected with Trans only or Trans+CXCR7. At 6 hours post-infection, media was replaced with media only or media containing (A) SDF-1/CXCL12 neutralizing antibody at 1.5, or 3.0 µg/ml or (B) ITAC/CXCL11 neutralizing antibody at 0.5 or 1.0 µg/ml. At 20 hours post infection, cells were lysed and analyzed by western blot for total Rb levels. Densitometry analysis was performed and fold change values were calculated from GAPDH-normalized optical density ratios as described for Figure 3. Bar graphs (bottom) represent the average fold change at each condition for two independent experiments.

Background: CXCL11/I-TAC
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.
