Fig. 4From: Prion infectivity is encoded exclusively within the structure of proteinase K-resistant fragments of synthetically generated recombinant PrPScThe recombinant prion infectivity is encoded within its PK-resistant protein conformation. a Samples from the same batch of recPrPSc were treated with PK as indicated. The lane marked by * was loaded with 5 times of PK-resistant recPrPSc (1 mg/mL, 37 °C, 16 h). b The prion infectivity of samples in (a) as evaluated by the Elispot cell infection assayBack to article page
