This antigen is “myelin base protein,” produced via recombinant DNA technology. It is one of the protein targets identified as an autoimmune antigen in multiple sclerosis (MS). I acquired this to try and treat MS, but it has never yielded any significant results. I have only used it in MS patients. I have since observed that the Lyme LDI mix most often works for MS. MBP is worth trying for MS patients who do not get 100% response with the Lyme mix.
