Western blot analyses of brain protease-resistant prion protein (PrPres) from BSE-H infected mice by using Saf84 monoclonal antibody. Tg110 mice infected with isolate 02-2695 (lanes 2 and 3) or 45 (lane 4) at first passage showing either high-type (lane 2) or classical BSE–like PrPres molecular profile (lanes 3 and 4). The BSE-H isolate (02–2695) (lane 1) and a BSE-C isolate (lane 5) were included for comparison. Similar quantities of PrPres were loaded in each lane. Values to the left indicate

Values to the left indicate molecular mass in kDa. BSE, bovine spongiform encephalopathy; BSE-H, unglycosylated PrPres that is higher than BSE-C; BSE-C, classical BSE.
