MOG (35-55), human is a component of CNS myelin. MOG (35-55), human is different from mMOG (35-55) by a proline for serine substitution at position 42. MOG (35-55), human is also immunogenic, but not encephalitogenic, and is only partially cross-reactive with mMOG35–55. MOG (35-55), human induces minimal clinical signs of EAE relative to the rodent peptide.
