Comparing Methods that Determine Empty-Full Ratio of AAV Capsids
The relative abundance of empty and full AAV capsids in gene therapy vector preparations is a critical quality attribute. A variety of methods are available to perform these measurements including SEC-MALS, which combines separation by size-exclusion chromatography with detection by multi-angle light scattering, UV/Vis, and differential refractometry. However, there are relatively few reports that compare these methods. This webinar compares the outcomes of numerous orthogonal characterization methods on a single vector preparation. We find that SEC-MALS not only provides favorable performance for quality control and product development applications, but that it is uniquely situated to be established as a platform method for the semi-quantitative measurement of empty/full ratios across AAV serotypes, transgenes, and manufacturing processes.
Key Learning Objectives:
- How SEC-MALS quantifies empty and full AAVs, as well as other attributes
- Are empty/full readouts from different assays comparable?
- Other light scattering techniques that quantify AAVs
Who Should Attend:
- CMC teams supporting AAV-based therapies
- Scientists involved in AAV characterization, analytical method development, process development, and quality control
- Lab managers that need to select and support an optimal set of AAV characterization methods
