Used in research and development of immunotherapies targeting inflammatory and autoimmune diseases. Binds specifically to the CXCR3 receptor, which is involved in T-cell and natural killer cell migration. This antibody helps modulate immune responses in conditions such as psoriasis, rheumatoid arthritis, multiple sclerosis, and transplant rejection. It serves as a reference standard in assays measuring CXCR3 expression and in validating new anti-CXCR3 therapeutic candidates. Also utilized in flow cytometry, immunohistochemistry, and functional blocking studies to investigate chemokine receptor signaling pathways.
