Prion - Wikipedia, The Free Encyclopedia
In general, prions are quite resistant to proteases, heat, ionizing radiation, and formaldehyde treatments, [67] although their infectivity can be reduced by such treatments. Effective prion decontamination relies upon protein hydrolysis or reduction or destruction of protein tertiary structure. ... Read Article
