MBP (85-99) peptide antagonist inhibits the binding of MBP 85-99 to HLA-DR2 and IL-2 and is a tool for MS research. The peptide antagonist is a 15-mer peptide that competes with Myelin Basic Protein MBP (85-99), the immunodominant epitope of MBP and major candidate autoantigen in multiple sclerosis (MS).
