METHOD FOR REMOVING PRION PROTEIN

摘要

The present invention relates to a method for removing prion PrPSc proteins from biological material by contacting a biological material comprising prion PrPSc proteins with sepharose under conditions that allow for the specific and high affinity binding of the sepharose to the prion PrPSc proteins and removing the biological material from the sepharose wherein the biological material is selected from mammalian urine or a fraction thereof or from cell culture-derived materials. Another aspect of the present invention concerns the use of specific and high affinity sepharose for removing prion PrPSc proteins from biological material.
