Purified recombinant Human ITAC protein Expression System: E.coli Bioactivity: Determined by its ability to chemoattract IL-2 activated T-cells using a concentration range of 0.1-10.0 ng/mL.
I-TAC is a 'non-ELR' CXC chemokine that is regulated by interferon and signals through the CXCR3 receptor. I-TAC is chemoattractant for IL2 activated T cells, but does not affect freshly isolated un-stimulated T cells, neutrophils, or monocytes. Alternative Names: B-R1 protein, CXCL11 protein
