PMCA on purified PrPC from brain tissue of sheep and deer. Lane 1, molecular weight marker (biotinylated). Lane 2, human recombinant PrP 23–231 was used as a positive control. Lanes 3 and 4, samples containing purified PrPC from brain tissue of sheep before and after PK digestion. Lane 5, PrPSc extracted from sheep brain as a reference after PK digestion with 10 times the reaction equivalents of the seed protein concntration. Samples of purified PrPC from brain tissue of sheep were incubated with preformed fibrillar seed of PrPSc round one (lane 6), round two (lane 7), PrPCWD (lane 8), ShY145Stop seeded with performed fibrils of ShY145Stop (lane 10), DeY145Stop (lane 11), or PrPSc (lane 12) after PK digestion.
