Used in research and development for immune-related diseases due to its specific targeting of interleukin-15 (IL-15). It serves as a critical tool in studying inflammatory and autoimmune conditions such as rheumatoid arthritis, inflammatory bowel disease, and multiple sclerosis. By neutralizing IL-15 activity, it helps elucidate the cytokine's role in T-cell and natural killer (NK) cell activation, survival, and proliferation. Frequently employed as a benchmark in assays, including ELISA and immunohistochemistry, evaluating new therapeutic antibodies or drug candidates targeting the IL-15 pathway, and for analyzing IL-15 expression in tissues or cells. Also utilized in preclinical studies to assess the potential of IL-15 blockade in transplant rejection and certain cancers, as well as to develop targeted treatments in immune-related diseases.
