This review discusses the importance of deep knowledge and control of a larger panel of culture components in mammalian cell cultures for process optimization, control, and robustness. It highlights key advances in microfluidic affinity assays and microchip capillary electrophoresis for the miniaturization and integration of Process Analytical Technology. The article also introduces a comprehensive toolbox of discrete analytical components that can potentially support the translation of mature microfluidic technologies towards novel applications.
Monitoring technologies for Process Analytical Technology (PAT) in mammalian cell cultures are often focusing on the same hand full parameters although a deeper knowledge and control of a larger panel of culture components would highly benefit process optimization, control and robustness. This short review highlights key advances in microfluidic affinity assays and microchip capillary electrophoresis (MCE). Aiming at the miniaturization and integration of PAT, these can detect at-line a variety of metabolites, proteins and Critical Quality Attributes (CQA's) in a bioprocess. Furthermore, discrete analytical components, which can potentially support the translation of increasingly mature microfluidic technologies towards this novel application, are also presented as a comprehensive toolbox ranging from sample preparation to signal acquisition.
