  10. Prions Prions are generally quite resistant to proteases, heat, radiation, and formalin treatments. Effective prion decontamination relies upon protein hydrolysis or reduction or destruction of protein tertiary structure. Examples include bleach, caustic soda, and strongly acidic detergents such as LpH. 134 °C (274 °F) for 18 minutes in a pressurized steam autoclave may not be enough to deactivate the agent of disease
