Technology
Dielectric spectroscopy (DS), also known as capacitance measurement, has been used as a PAT tool for vaccine and viral vector production processes (adenovirus, lentivirus reovirus, influenza, baculovirus) with mammalian and insect cells. It has been viewed as an important process control tool for continuous virus production processes.
Numerous groups have explored this technology to monitor live cell density, identify critical events and control the process. The benefits of using capacitance technology in these applications are multifold. Considering capacitance measurement correlates with the live cell density (or more accurately, viable biovolume) profile of the culture, it provides a complete, real time and detailed picture of all of the critical events. This leads to better process monitoring, automation and control and in turn, improved productivity.
