Detection of SH aPrP (90-231) by ELISA with antisera from prion immunized Prnp0/0/Balbc/J, but not wt Balbc/J mice. Antisera from Prnp0/0/Balbc/J mice detected SH aPrP (90-321) at dilutions >1:30 K by direct binding ELISA; whereas antisera from immunized wt Balbc/J mice failed to detect SH aPrP (90-231) at any dilution (A). Antisera from prion immunized Prnp0/0/Balbc/J, but not wt mice, detected SH aPrP (90-231), Syrian hamster brain PrPC (Ha PrPSc DRM; no PK) and PrPSc (Ha PrPSc DRM; +PK) by Western blot (B). Detection of PK-resistant PrPSc was observed with antisera diluted >25 K from two representative Prnp0/0/Balbc/J (#1–2) and wt Balbc/J (#3–4) mice immunized with purified prion antigen.
