    The present study has investigated central nervous system disease in guinea pigs inoculated with emulsions containing purified preparations of bovine oligodendroglia and their fractions isolated with or without trypsinization, whole bovine white matter or myelin basic protein (MBP). The MBP content of the oligodendroglial fractions was determined by radioimmunoassay. It was found that oligodendroglia prepared from trypsinized fresh brain contained minute amounts of MBP and did not induce disease. The corresponding cell fraction from non-trypsinized frozen brain was rich in MBP and induced disease. Bovine white matter and MBP induced typical experimental allergic encephalomyelitis (EAE). The structural preservation of the non-encephalitogenic trypsinized MBP-poor cells was very good and that of the encephalitogenic MBP-rich non-trypsinized cells very poor. It has been concluded that the encephalitogenicity observed was due to MBP, rather than to a specific oligodendroglial antigen.
