Abstract
The present invention relates to an in vitro method for detecting a pathogenic conformational isomer of the prion protein in a sample, said method comprising a preliminary step for capturing the pathogenic conformational isomer by putting the sample into contact with nanobeads covered with a ligand of the pathogenic conformational isomer, and then applying a cyclic amplification of the misfolded prion protein directly on the solid support having captured the pathogenic conformational isomer, and detecting the presence of the pathogenic conformational isomer. The invention also relates to a kit for applying this method and to a method for decontaminating a biological sample.
