Method for inactivating prions
Abstract
It is intended to eliminate prions, viruses and other infectious agents present in biological or biogenic materials, eg, in a plasma or serum from which albumin is derived, without adversely affecting the biological material. For this purpose, the biological or biogenic material is treated according to the invention with a chaotropic reagent, for example with urea or sodium thiocyanate, for about 18 hours. Previously, a detergent, for example, sodium lauryl sulfate, and methyl or ethyl alcohol may be added and the solution heated to about 70 ° C for about 30 minutes. After cooling and acidification, the globulins can be separated off.
