Myelin oligodendrocyte glycoprotein (MOG) 40-54, a minor component of CNS myelin, is expressed in central nervous system myelin which produces a relapsing-remitting neurological diesease with extensive plague-like demyelination. It is believed to be a target autoantigen in multiple sclerosis. MOG 40-54 peptide is an immunodominant epitope of MOG that induces strong T and B cell responses and Induces experimental autoimmune encephalomyelitis in rodents. A single injection of this peptide produces a relapsing-remitting neurologic disease with extensive plaque-like demyelination. This Cysteine containing MOG 40-54 peptide can be use to induced polyclonal anti-MOG(40-54) antibody production in rabbits with high specificity, high affinity, and high titer indicating its high purity, as well as suitability for peptide-coated ELISA and Western blot assay. Immunization with MOG (40-54) suppresses spontaneous regeneration of dopaminergic neurons injured with MPTP.
