The second half of this article describes the testing methods used by the authors to demonstrate the applicability of single-use mixing technology for virus inactivation.
The potency of recombinant proteins such as monoclonal antibodies remains typically unaffected by detergent-based virus inactivation treatments because detergents tend to target lipids and lipid derivatives rather than proteins. Virus inactivation treatments that use detergents are robust with respect to temperature, which allows these steps to be performed at room temperature without thermoregulation. In this two-part article, the authors describe the testing performed to demonstrate the applicability of single-use mixing technology for a virus inactivation step performed using detergent.
