abstract：:The conversion of the cellular isoform of the prion protein (PrP(C)) into the pathologic isoform (PrP(Sc)) is the key event in prion diseases. To study the conversion process, an in vitro system based on varying the concentration of low amounts of sodium dodecyl sulfate (SDS) has been employed. In the present study, t...
