Adeno-associated virus (AAV) is a common delivery vehicle in gene therapy. Robust, rapid and automated characterization methods are imperative for commercialization of AAV-based products. However, standard methods are labor- and time-intensive, requiring costly reagents. In this presentation, we will discuss a method to measure three critical quality attributes (CQAs) of AAVs:
- Total number of viral capsid particles;
- Relative capsid content (e.g., fraction of full capsids);
- Percentage of monomer or aggregates. The highly precise SEC-MALS method utilizes multi-angle light scattering in line with standard size-exclusion chromatography, requiring little sample prep, no reagents and minimal operator effort.
Learning objectives:
- How light scattering combines with SEC and other detectors to provide comprehensive biophysical analysis of AAVs
- How SEC-MALS can be positioned as a platform technology in AAV development and production
