Assessing Your AAV Product Quality? Get the Confidence You Need With Maurice

Viral capsid content can impact gene therapy product efficacy and is therefore considered a Critical Quality Attribute (CQA) that must be properly evaluated during the development and manufacturing of AAVs. Traditional analytical tools such as transmission electron microscopy (TEM), analytical ultracentrifugation (AUC), and ion-exchange chromatography (IEX) can be used to characterize capsid content but are complex, labor-intensive, and pose challenges in data reproducibility, throughput, and scalability.

In this application note, we show how imaged capillary isoelectric focusing (icIEF) technology on the Maurice system can be used to characterize empty, intermediate and full AAV capsids at native and stability screening conditions, providing robust and reproducible data. With this, the Maurice system provides crucial data to aid in developing the right formulation for AAV therapeutics.
