FAQ
Which 293 cell lines are compatible with this expression system?
This system is validated for a wide range of suspension 293 cell lines, including HEK293F and HEK293S.
Is this expression system entirely serum-free?
Yes. All components of the system are 100% serum-free.
What is the optimal timing for protein harvest?
For secreted proteins, we recommend harvesting when cell viability drops to ≤60%.
For intracellular or membrane proteins, harvest at a viability threshold of ≤85%, or adjust based on the specific protein stability.
Can I purify my protein from 293F Hi-Exp Feed using Strep-tag or His-tag purification systems?
For intracellular or membrane proteins, the medium is fully compatible with Strep-tag or His-tag purification systems.
For secreted proteins, the medium can be compatible with His-tag purification systems, but it is not directly compatible with Strep-tag purification systems. It is recommended to perform a buffer exchange or dialyze the samples before Strep-tag purification.
