Abstract
The present invention is for improved methods of inactivating viruses in a sample by exposing the sample to a combination of pressure treatment and exposure to an inactivating agent. The sample can be repeatedly cycled between relatively high and low pressures and the inactivating agent is selected from ethyleneimine, ethyleneimine oligomers, psoralens, DNase and RNase.

A method of inactivating viruses in a sample, comprising the steps of:
- a) adding an inactivating chemical to the sample;
- b) exposing the sample to an elevated pressure;
- c) releasing the pressure;
- and
- d) recovering the sample.
A method of inactivating viruses in a sample, comprising the steps of:
- a) adding an inactivating chemical to the sample;
- b) exposing the sample to an elevated pressure;
- c) releasing the pressure;
- d) irradiating the sample with UV light;
- e) recovering the sample.
