背景介绍 The CXC chemokine ligand 11 (CXCL11) or IFN-inducible T-cell-chemoattractant (I-TAC) belongs to the CXC chemokine family characterized by the presence of 1 amino acid in between the 2 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 resulted in a synergistic increase of CXCL11 production. CXCL11 attracts activated T-helper 1 (Th1) lymphocytes and natural killer (NK) cells. Like CXCL9 and CXCL10, CXCL11 signals through CXC chemokine receptor 3 (CXCR3). 产品介绍 Recombinant human CXCL11 (ITAC) is a disulfide-linked monomeric protein consisting of 74 amino acid residues and migrates as an approximately 8 kDa protein under non-reducing conditions and reducing conditions in SDS-PAGE. Optimized DNA sequence encoding Human ITAC (CXCL11) mature chain was expressed in E. coli.
