Fig. 5. Western blot analysis of sheep PrPC and of proteinase K-treated PrPSc and PrPC used for the ELISA: proteinase K digestion of the brain homogenates as described in Materials and Methods. Lane 1, normal sheep brain homogenate; lane 2, proteinase K-digested infected sheep brain homogenate; lane 3, proteinase K-digested normal sheep brain.

Fig. 6. ELISA titration of PrPC and of proteinase K (PK)-treated PrPC and PrPSc from mouse (Mo), hamster (SHa), and macaque (Ma). PrPC samples are from brains of normal mouse, hamster, and macaque. PrPSc is produced by proteinase K treatment of homogenates of brains infected by scrapie for mouse and hamster and by bovine spongiform encephalopathy for macaque. The proteinase K-treated PrPC samples are used as a control for total digestion of PrPC. (Top) Mouse. (Middle) Macaque. (Bottom) Hamster.
