Biotechnology Progress, EarlyView.Abstract The possibility to produce recombinant adeno‐associated virus (rAAV) by adherent HEK293T cells was studied in a stirred tank bioreactor (STR) culture of cell aggregates. A proof‐of‐concept of rAAV production was successfully demonstrated in a process where single cells were first expanded, then cell aggregates were formed by dilution into a ...

Iterative hybrid model based optimization of rAAV production
Biotechnology Progress, EarlyView.Abstract Changes in serotype or genetic payload of recombinant adeno associated virus (rAAVs) gene therapies require adapting the transfection conditions of the upstream HEK293 cultivations. This study adopts an iterative model‐based experiment design approach, where increasing data availability is leveraged to evolve models of different complexity ...

Elasticity Theory and Shape Transitions of Viral Shells
, 2005 Recently, continuum elasticity theory has been applied to explain the shape transition of icosahedral viral capsids - single-protein-thick crystalline shells - from spherical to buckled/faceted as their radius increases through a critical value ...

A synthetic platform for developing recombinant adeno‐associated virus type 8 producer cell lines
Biotechnology Progress, EarlyView.Abstract Recombinant adeno‐associated virus (rAAV) is one of the most widely used viral vectors for gene therapy. It is used in very high doses for the treatment of many diseases, making large‐scale production for clinical applications challenging. We have established a synthetic biology‐based platform to construct stable production cell lines, which ...
