The CXCL11 belongs to the CXC chemokine family characterized by the presence of one amino acid in between the two NH2-terminal cysteines. CXCL11 is produced by a variety of cells including leukocytes, fibroblasts, and endothelial cells upon stimulation with interferons (IFNs). Simultaneous stimulation of fibroblasts or endothelial cells with IFN-gamma and Interleukin-1b or the TLR3 ligand double-stranded RNA results in a synergistic increase of CXCL11 production. CXCL11 attracts natural killer cells and activated T-helper 1 cells. Like CXCL9 and CXCL10, CXCL11 signals through CXC chemokine receptor 3 (CXCR3).
Aliases- CXCL11, C-X-C motif chemokine 11, Beta-R1, H174, Interferon gamma-inducible protein 9, IP-9, Interferon-inducible T-cell alpha chemoattractant, I-TAC, µmall-inducible cytokine B11
- Recombinant Human IFN-Inducible T-cell Chemoattractant (CXCL11)
Formulation- Lyophilized from a 0.2 µm filtered solution in PB,100 µm NaCl pH 7.5
Endotoxin Level- <1.0 EU/µg of recombinant protein as determined by the LAL method.
Storage Condition- The lyophilized protein is stable for at least one year from date of receipt at -70°C. Upon reconstitution, this cytokine can be stored in working aliquots at +2° to +8°C for one month, or at -20°C for six months, with a carrier protein without detectable loss of activity. Avoid repeated freeze/thaw cycles.
