ABSTRACT:
The invention relates to compositions and methods for prion degradation, decontamination or disinfection. The composition comprises an oxidizing agent, one or more proteases and a surfactant such as an ionic surfactant/detergent. The method comprises contacting a prion contaminated entity with a prion-degrading composition comprising an effective amount of an oxidizing agent, an effective amount of at least one protease, and an effective amount of a surfactant. The components of the composition may be contacted with a prion-contaminated entity sequentially or simultaneously using an aqueous composition. Typically at least two different proteases are used for optimal efficacy. Preferably the oxidizing agent comprises peracetyl ions or a source thereof. The invention also relates to kits comprising the various reagents.
