Integration of Monolithic Analytical Columns Into the Biopharmaceutical Manufacturing Process to Enable Fast and Real-time HPLC Analytical Assay Both Up- and Downstream

Biomanufacturing of antibodies, therapeutic proteins and vaccines or gene delivery vectors (either DNA or virus based) is a very complicated process where many things can go wrong. This is even more pronounced as the target biomolecules are extremely susceptible to the environmental conditions both during cultivation (upstream processing) as well as during isolation and purification (downstream processing). One can always doubt whether we have enough information about our complex biomolecule samples to consistently develop a safe product by running a robust and efficient purification bioprocess.

By using and understanding novel technologies one can design new process analytic technology (PAT) initiatives to overcome some of these problems. Here, we present novel monolithic analytical columns — CIMac columns — that can bridge this gap. In the first example, CIMac columns were applied for monitoring the purification process of virus like particles (VLP) which are used for production of vaccines and as delivery systems in gene therapy. In the second example, the monolithic analytical columns were also applied for monitoring the fermentation process of bacteriophages.
