Assessment of prion inactivation by fenton reaction using protein misfolding cyclic amplification and bioassay.
An abnormal isoform of the prion protein, associated with transmissible spongiform encephalopathies, retains infectivity even after undergoing routine sterilization processes. We found that a formulation of iron ions combined with hydrogen peroxide effectively reduced infectivity and the level of abnormal isoforms of the prion protein in scrapie-infected brain homogenates. Therefore, the Fenton reaction has potential for prion decontamination.
