Used in neuroscience research to study peripheral nerve myelination and autoimmune responses linked to peripheral neuropathies. Serves as an antigenic peptide to induce experimental autoimmune neuritis (EAN), a model for Guillain-Barré syndrome (GBS), enabling investigation of disease mechanisms and potential immunotherapies. Also employed in T-cell proliferation assays and epitope mapping to understand immune recognition in neuroinflammatory conditions.
