AAV process development
Our HEKExpress® cell host’s unique efficiency in producing AAV is the result of over twenty years of innovation and fine-tuning. The highlights:
High titers
— up to 1 × 1015 vg/L
Any serotype, any Gene of Interest
HEK293 cells in suspension adapted in ACF
Robust cells for scalable processes
— up to 40 L
cGMP compliant
— fully characterized MCB
What properties make HEKExpress® such an efficient cell host?
High viable cell densities
Over 107 cells/mL without feed
Fast doubling time
Under 24 hours
Absence of SV40 large T antigen
Very low aggregation in STR
Leading know-how in HEK process optimization
Your serotype and Gene of Interest are optimally expressed, and we provide the following: high AAV productivity, a scalable process ready for transfer and speed with high throughput screening.
DOE for process optimization at 10 mL scale
Bioreactor runs up to 40 L scale
Downstream process development, serotype-specific development
Analytics development (dPCR, SEC-MALS, DLS, thermal shift...)


Process optimization
2× Improvement in VCD Compared to Commercially Available HEK293

10× Improvement in Yield from AAV2-GoI Process Optimization
