Used in immunological research to study multiple sclerosis (MS) and other autoimmune diseases. It serves as a peptide fragment of myelin basic protein (MBP), which is a key component of the myelin sheath in the nervous system. Researchers utilize it to investigate immune responses, particularly T-cell reactivity, in the context of MS. It helps in understanding the mechanisms of autoimmunity and in developing potential therapeutic strategies. Additionally, it is employed in experimental models to simulate and analyze the pathological processes associated with demyelinating diseases.
