BIA Separations, a bio-chromatography development and manufacturing company, has announced the introduction of its novel PrimaS™ ligand technology. The proprietary multi-use platform facilitates high-resolution and high speed processing and addresses many underserved but critical separation problems in the context of fast emerging advanced therapy medicinal products (ATMPs). The first application of PrimaS technology being made available is for mRNA purification addressing a rapidly growing interest in mRNA-based therapies.

As part of BIA Separations‘ CIMmultus™ range, PrimaS is a key addition to the company‘s mRNA purification toolbox, including Oligo dT-18, C4-HLD and SDVB chemistries. The platform harnesses mRNA capturing and polishing strategies, including dsRNA impurity removal and mRNA sizing options. All technologies are easily scalable from lab to manufacturing, and are able to provide better product quality than traditional purification systems.

mRNA manufacturing involves several complex bioprocessing steps beginning with plasmid DNA production and its linearization, followed by in vitro transcription (IVT). Both operations include finely balanced enzymatic reactions, utilizing a number of key raw materials. For the standards required for clinical applications, ultra-pure mRNA is required, with critical contaminants eliminated, including dsRNA, template DNA and respective enzymes, in addition to potential impurities from raw materials such as chromatin-like structures and endotoxins.
