Used to quantitatively measure interferon-inducible T-cell alpha chemoattractant (I-TAC/CXCL11) in human biological samples such as serum, plasma, or cell culture supernatants. This ELISA kit is particularly useful in immunology and inflammation research, helping assess immune activation and T-cell recruitment in conditions like autoimmune diseases, viral infections, and cancer. It enables researchers to study the role of CXCL11 in disease progression and response to therapy with high sensitivity and specificity.
