  • Publication number: 20050089943
    Abstract: The invention provides a rapid, sensitive immunoassay capable of detecting and quantitating pathogenic protein to a level of 3 to 5 logs. The preferred immunoassay utilized is a chemiluminescent endpoint for a Western blot immunoassay. The invention has been successfully applied to track the clearance of pathogenic protein during production of proteins derived from plasma. It is particularly applicable and has been confirmed by bioassay to relate TSE infectivity to quantitative results on prion protein.

  • Publication number: 20050054003
    Abstract: A method of preparing a solution containing biological material by adding a fumed metal oxide and/or particulate silicon dioxide to biological material to obtain a mixture of fumed metal oxide and/or particulate silicon dioxide and the biological material; and separating the fumed metal oxide and/or particulate silicon dioxide from the mixture to form a resulting solution, wherein any pathogenic prion proteins possibly contaminating the biological material are substantially reduced in the resulting solution.
