Chemical inactivation
WebMay 28, 2024 · Viral inactivation is a well-understood process and relies on a number of parameters. Two critical parameters are pH and exposure time, with acid selection, protein concentration, and temperature also of high importance. While lower pH setpoints can reduce the time needed for inactivation, this typically incurs greater risk of protein damage.
