Figure 2. Representative Western blot analyses of protease-resistant prion protein (PrPres) in H-type (lanes 2, 3), L-type (lanes 5, 6), and C-type (lanes 1, 4, 7) cases of bovine spongiform encephalopathy (BSE). Bars to the left of the panels indicate the 29.0-, 20.1-, and 14.3-kDa marker positions. H-type, higher molecular masses of unglycosylated PrPres; L-type, lower molecular masses of unglycosylated PrPres; C-type, classic BSE. Monoclonal antibodies Sha31 and SAF84 were used for PrPres detection in panels A and B, respectively.
