Human I-TAC (CXCL11) Recombinant Protein

Human I-TAC (Interferon-inducible T cell alpha chemoacttractant) is an 8.3 kDa protein containing 73 amino acid residues. I-TAC is a novel non-ELR CXC chemokine. It is regulated by Interferon and has potent chemoattractant activity for IL-2 activated T cells, but not for freshly isolated unstimulated T cells, neutrophils, or monocytes.
