Immunolabeling abnormal prion protein using immunohistochemistry protocols requires specific sample and anti-PrP antibody preparation methodologies. The present protocol describes the key steps in epitope demasking to ensure proper PrP immunolabeling and to minimize non-specific background staining. Also, this approach considers biosafety measures when conducting immunohistochemistry studies with the prion-infected tissues.
