Outline of Final Research Achievements |
We used size exclusion gel chromatography to evaluate oligomeric prion protein on some human prion diseases. In all examined samples (sporadic Creutzfeldt-Jakob disease (CJD), CJD with E200K mutation, CJD with V180I mutation, Gerstmann-Straussler-Scheinker disease (P102L), D178fs25 Prion disease), oligomeric fraction contained a lot of proteinase K resistant prion protein (PrPres), respectively. Low molecular PrPres detected in some kinds of prion diseases were also contained in the oligomeric fraction. Our results suggested that PrPres tends to form oligomeric state.
