Event: Cell and Gene Therapy Insights webinar (February 17, 2022)
Presenter: Ales Strancar, Managing Director
Title of the lecture: AAV manufacturing process development using fast USP and DSP biochromatography analytics

Key learning points:
- One of the key challenges in manufacturing viral vectors is to increase the ratio between empty and full capsids.
- When the expression in the cell line results in less than 10% full capsid it is quite impossible to reach better than 90% full in the final product. It is therefore mandatory to optimise the USP to result in better empty/full ratio.
- This can be efficiently realised by using at-line PATfix to allow for analysis of the full and empty capsids ratio directly in the harvest.
- The residual empty capsids can be removed by polishing step using different anion exchange columns.
