In vitro polymerization of glial fibrillary acidic (GFA) protein extracted from multiple sclerosis (MS) brain

Abstract
Aqueous extracts of multiple sclerosis plaques were used for reaggregation studies of filamentous proteins. Filament formation as observed by electron microscopy was dependent on temperature, pH, and energy. The major protein component in the filaments had chemical and immunological properties of the glial fibrillary acidic protein.
