Less Is More in mRNA Therapeutics: Developing Big Ideas at Small Scales

In a November 2022 webinar, Linda Mathiasson (strategic customer lead at Cytiva) discussed the significant promise of messenger ribonucleic acid (mRNA), its role in fighting genetic and infectious diseases, and how its production can be scaled to meet the needs of different applications, ranging from large-scale vaccination to production of individual therapies. The Presentation Thanks to the rapid development of mRNA vaccines for COVID-19, the biopharmaceutical industry has gained momentum toward realizing the technology’s potential. The speed, flexibility, and low-cost…

The Use of Dynamic Control in Periodic Counter-Current Chromatography

The interest in continuous bioprocessing to introduce productivity gains and cost savings is rapidly growing. Periodic counter-current chromatography (PCC) is one suitable technological approach, enabling continuous downstream processing. However, implementation in downstream applications is still uncommon mainly due to perceived complexity in operation and process control strategies. This work demonstrates the dynamic control function of ÄKTA™ pcc 75 chromatography system when applied to a protein A capture step operated in a three-column PCC (3C PCC) setup. Dynamic control enables sample…
