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.

Specificity
Detects human CXCL11/I-TAC in ELISAs and Western blots. In ELISAs, this antibody does not cross-react with recombinant human (rh) CXCL5, 7, 8, 9, or 10. In Western blots, this antibody shows less than 1% cross-reactivity with rhCXCL1, 2, 3, 5, 6, 7, IL-8/CXCL8, 9, 10, 13, CXCL12/SDF-1 alpha, CXCL12/SDF-1 beta, rmCXCL1, 2, 6, 9, 10, CXCL12/SDF-1 alpha, rmCXCL13, rrCXCL1, CXCL3/CINC-2 alpha, CXCL3/CINC-2 beta, or rpIL-8/CXCL8.

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 (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 (AR002). Chemotaxis elicited by Recombinant Human CXCL11/I‑TAC (15 ng/mL) is neutralized (green line) by increasing concentrations of Human CXCL11/I-TAC Monoclonal Antibody (Catalog # MAB672). The ND50 is typically 0.0400‑0.480 µg/mL.Detection of CXCL11/I-TAC by Western Blot
CXCL10 cleavage by GP63 occurs between positions A81 and I82.(B) GP63 selectively cleaves chemokine ligands of the CXCR3 receptor. Conditioned media from L. major WT, delta gp63, and delta gp63+1 was incubated with human recombinant chemokines for 12 h and product detected by western blot. Cleavage is only detected for the CXCL9/10/11 family. Representative blots are shown from at least two independent experiments.

1 µg/mL
Sample: Recombinant Human CXCL11/I-TAC (Catalog # 672-IT)
Sample: Recombinant Human CXCL11/I-TAC (Catalog # 672-IT)
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 0.0400-0.480 μg/mL in the presence of 15 ng/mL Recombinant Human CXCL11/I-TAC.
