This work shows that DHM can be implemented for online monitoring of Sf9 concentration and viability, as well as product titer (AAV) or culture progression in lytic systems. Therefore, it is a valuable tool to support the time of harvest decision and establishing controlled feeding strategies.

The insect cell-baculovirus vector system has become one of the favorite platforms for the expression of viral vectors for vaccination and gene therapy purposes. Because it is a lytic system, it is essential to balance maximum recombinant product expression with harvest time, minimizing product exposure to detrimental proteases. With this in mind, new bioprocess monitoring solutions are needed to accurately estimate culture progression. Herein, we used online digital holographic microscopy (DHM) to monitor bioreactor cultures of Sf9 insect cells
