Addressing the challenges of purification & quality control in gene therapy

Thursday 24th June 2021 8:00 PDT; 11:00 EDT; 16:00 BST; 17:00 CEST

Recombinant Adeno Associated Virus (rAAV) vectors are one of the most promising mechanisms for therapeutic gene delivery. However, most industrial cell lines exhibit inefficient gene packaging which results in a heterogenous population of vectors composed of empty, partially-loaded, and fully-loaded species. Purifying, identifying, and quantifying these different species is vital from a production and quality control standpoint, since improperly loaded viral capsids do not produce the desired therapeutic effect but may still elicit an unintended immune response.

In this Beckman Coulter Life Sciences webinar, our panelists will focus on several pertinent topics in rAAV process development including current challenges, technologies for overcoming quality control hurdles, best practices for downstream processing, as well as discuss the current trends and future outlook of this rapidly growing therapeutic frontier.

Attendees will learn:

  • Understand the challenges of differing serotypes in rAAV production and quality control
  • Understand the commonly used characterization techniques for AAV capsids
  • Understand the basics of Analytical Ultracentrifugation (AUC) and how it is used to characterize empty, full, and intermediate AAV capsids
  • Learn about best practices in Density Gradient Ultracentrifugation (DGUC) to achieve highest purity in gene therapy products

Further panellists to be announced soon.

Dr. Akash Bhattacharya

Senior Application Engineer, Beckman Coulter Life Sciences

Akash Bhattacharya graduated from Presidency College, India with a major in Physics and went on to a Masters’ in Physics at the Indian Institute of Science where he worked on Quantum Computing. He then moved for doctoral studies in Biophysics to the University of Michigan, Ann Arbor where he joined the lab of Prof. Erik Zuiderweg and worked on NMR spectroscopy methods development in the context of the Structural Biology of Chaperone Proteins.

After Michigan, he worked briefly at Rutgers and then eventually moved to the Dept. of Biochemistry and Structural Biology at the University of Texas Health at San Antonio. Here, he worked with Prof. Dmitri Ivanov and Prof. Borries Demeler on the enzymology of HIV infection and restriction by mammalian proteins. He also worked on projects related to oncology (DNA damage repair) and neuroscience (voltage gated ion channels), using a wide variety of techniques ranging from X-ray crystallography, NMR spectroscopy, fluorescence spectroscopy, molecular dynamics and analytical ultracentrifugation (AUC).

He collaborated with Prof. Demeler to extend AUC methods to novel enzymatic systems resulting in publications in PNAS, Cell Reports, Nature Scientific Reports, etc. Akash joined Beckman Coulter Life Sciences in Oct 2018. He is based in the Colorado R&D center and works on developing new AUC applications. His research interests include extending AUC methodology to new therapeutic areas such as AAV capsids (gene therapy), liposomal drug carriers and others.
