A Holistic Approach to AAV Advanced Analytics

This webinar will discuss some of the advanced analytical capabilities available to Pharmaron for AAV characterisation.

View on demand. 

Key messages: 

  • AAV analytical testing must overcome a range of challenges associated with the complexity of the viral vector format: ​
    • High molecular mass and level of heterogeneity (capsid composition, payload e.g., empty, partial, full)​
    • Diverse range of post translational modifications​
    • Host cell protein from expression system​
  • Techniques used routinely for characterisation of other advanced therapies do not necessarily translate to AAV analysis
  • Understanding of challenges posed based on serotype need to be considered and addressed
  • New technologies will be important in meeting some of the challenges of AAV analysis e.g., mass photometry, CDMS, IMS-MS


  1. What are the challenges associated with AAV analytics?  (KOL)​
    • Heterogeneity and mass of AAV material​
    • Post translation modifications and CQA identification​
    • Protease resistance of particular AAV serotypes​
    • HCP detection​
  2. What is Pharmaron's current approach? (Pharmaron)​
    • Peptide mapping approach for sequence and PTM determination​
    • Intact mass methods for identity confirmation and potential PTMs​
    • Innovative approach to protease digestion​
    • Leverage of wide-ranging technologies ​
    • Collaborative approach to method development and assessment of new technologies​
  3. Charge Detection Mass Spectrometry (CDMS) (University of Manchester)​
    • Introduction to CDMS​
    • Characterisation of AAV Payload Status​
    • Future Developments

Key Opinion Leader: Professor Perdita BarranChair of Mass Spectrometry at the School of Chemistry, University of Manchester 

Professor Perdita Barran is Chair of Mass Spectrometry at the School of Chemistry and Director of the Michael Barber Centre for Collaborative Mass Spectrometry at the University of Manchester. The Barran Group have developed IM-MS instrumentation to investigate changes in protein conformation and aim to understand biological systems using mass spectrometry-based techniques in conjunction with collaboration with biologists and biomedical research groups. In 2009, in recognition of her achievements Barran was awarded the inaugural Joseph Black award by the RSC Analytical Division.


Paul Getty - Senior Technical Scientist, Analytical Sciences, Pharmaron Gene Therapy

Paul is a Senior Technical Specialist within the Analytical Development Group at Pharmaron, Liverpool. He has 7 years’ experience in the biopharmaceutical industry working on analytics of a wide range of therapeutics. In his current role, Paul is responsible for identification/investigation of new technologies and development of analytical methods designed to support characterisation of viral vectors.

Ellen LiggettPhD Student (Barran Group), BBSRC DTP CASE, Department of Chemistry, University of Manchester

Ellen is in the second year of her PhD in the Barran Group at the University of Manchester, funded by the BBSRC and linked with Pharmaron. Having gained Mass Spectrometry experience at both GlaxoSmithKline and Allergan Biologics (now Pharmaron), Ellen is now working with Ion Mobility and Mass Spectrometry techniques applied to the study of viruses such as SARS-CoV-2 and AAVs in diagnostics and therapies, respectively.
