Used in research to study inflammatory and autoimmune diseases such as psoriasis, rheumatoid arthritis, and multiple sclerosis. Binds to IL-17 cytokines, helping block their activity and reduce inflammation in experimental models. Employed in protein interaction studies and immunoassays due to the Fc tag, which allows for easy detection and purification. Supports development of therapeutic antibodies by serving as a target antigen in screening and neutralization assays.
