背景介绍 Thymus and activation-regulated chemokine (TARC) is a recently identified CC chemokine that is expressed constitutively in thymus and transiently in stimulated peripheral blood mononuclear cells. TARC functions as a selective chemoattractant for T-cells that express a class of high affinity receptors binding TARC. The chemokine TARC is a ligand for the chemokine receptor CCR4 expressed on T helper (Th)2- type CD4 T cells. 产品介绍 Recombinant TARC (CCL17) is a disulfide-linked monomeric protein consisting of 72 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 TARC (CCL17) mature chain was expressed in E. coli.
