HEKstar 293
Defining Performance in Stable Expression
Specifically designed for stable recombinant protein expression in HEK293 cells, our solution supports high cell densities in scalable batch and fed-batch processes, giving you flexibility in production.
The chemically defined, protein-free formulation eliminates animal-derived components, reduces variability, and simplifies downstream processing. At the same time, it ensures robust suspension adaptation, stable growth kinetics, and consistently high cell viability above 90%.
