CA 2725100

A method for efficiently amplifying abnormal prion protein (PrP Sc) derived from bovine spongiform encephalopathy (BSE) is provided. Ultimately, the invention aims at eradicating the transmission of a prion disease by detecting a BSE-infected cow early and developing a method for inactivating prions and permitting early examination of prion inactivation. Provided is a method for efficiently amplifying PrP Sc derived from BSE, wherein the method is based on a PMCA (protein misfolding cyclic amplification) method in which normal prion protein (PrP c) is used as a source and PrP Sc is used as a seed, and PrP Sc derived from BSE is amplified by stir-mixing, incubating, and sonicating both the PrP c and the PrP Sc repeatedly, and wherein the method includes performing stir-mixing--incubation-sonication in the presence of a polysaccharide sulfate.

L'invention a pour objet de fournir une méthode d'amplification efficace d'une protéine prion anormale (PrPSc) dérivée de l'encéphalopathie spongiforme bovine (ESB), afin de trouver un bovin infecté par l'ESB à un stade précoce en vue d'éradiquer la propagation de la maladie du prion, et afin de permettre le développement d'une méthode d'inactivation de prion et l'évaluation de l'inactivation de prion à un stade précoce. Ainsi, l'invention concerne une méthode d'amplification efficace d'une protéine prion anormale (PrPSc) dérivée de l'ESB par une méthode PMCA (amplification cyclique du mauvais repliement des protéines) dans laquelle une PrPSc dérivée de l'ESB est amplifiée par utilisation d'une protéine de prion normale (PrPC) en tant que source et de la PrPSc en tant que germe et mise en oeuvre du mélange pendant agitation/culture et le traitement par ultrasons de la PrPC et de la PrPSc de manière répétée, le mélange pendant agitation/culture et le traitement par ultrasons étant mis en oeuvre en présence d'un polysaccharide sulfaté.
