摘要 |
The invention relates to a method for diagnosing a transmissible spongiform subacute encephalopathy (TSSE) caused by an unconventional transmissible agent (UTA) or prion. The method involves treating a sample suspected of containing a prion with proteinase K for a time and under conditions that completely degrade normal prion protein (Prp-sen), but which only partially digest abnormal prion protein (PrP-res) so that all or some of the octapeptide motif repeats comprising P(H/Q)GGG(-/T)WGQ (SEQ ID NO: 1) in the abnormal prion protein (Prp-res) are retained. |
