  • Nanobeads covered with plasminogen as a direct support for cyclic amplification of the prion protein PrP
    Patent number: 8859298
    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.
    Type: Grant

  • USE OF DELEUCOCYTATION FILTERS FOR DEFENSIN PURIFICATION
    Publication number: 20100291629
    Abstract: The invention concerns the use of deleucocytation filters for defensin purification. More precisely, the invention concerns a method for purifying defensins, including the following steps: passing a blood sample on a deleucocytation filter; detaching the cells retained on the deleucocytation filter, inducing exocytosis of the defensins by those cells.
