Use of a new immunoassay to measure PrP Sc levels in scrapie-infected sheep brains reveals PrP genotype-specific differences.

Abstract excerpt

The diagnosis of prion diseases, such as scrapie and BSE, has traditionally relied upon the identification of the disease-associated form of the prion protein, PrP(Sc), based on its resistance to digestion by proteinase K (PK). A more recent development is the conformation-dependent immunoassay (CDI), which distinguishes between PrP Sc and normal PrP (PrP C) based on their differing solubility in guanidine...
