Used in the development of therapies targeting inflammatory and autoimmune diseases by neutralizing CXCL9, a chemokine involved in T-cell recruitment. This antibody helps modulate immune responses in conditions such as psoriasis, lupus, and rheumatoid arthritis. It is also investigated for use in transplant rejection and chronic inflammatory disorders due to its role in suppressing T-cell-mediated inflammation. Its high specificity makes it valuable in diagnostic assays and as a reference standard in drug development.
