Used in research related to multiple sclerosis, particularly in studies involving the immune response in experimental autoimmune encephalomyelitis (EAE) models. This peptide fragment serves as an antigenic epitope to induce T-cell activation and investigate mechanisms of neuroinflammation. It helps in understanding antigen presentation, immune tolerance, and potential therapeutic interventions targeting autoimmune reactions in the central nervous system. Commonly employed in immunological assays such as T-cell proliferation tests, cytokine profiling, and epitope mapping.
