PRION CLEARANCE USING PARTICULATE METAL OXIDES

摘要

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.
