よくあるご質問(FAQ)
My ExpiFectamine CHO Transfection Kit (Catalog No. A29130) was accidentally frozen. Can I still use it?
ExpiFectamine reagents generally does not transfect well after being frozen, as the freezing disrupts the lipid micelles. Therefore, we do not recommend using this kit.
Do you offer the ExpiFectamine CHO Transfection Enhancer, from the ExpiFectamine CHO Transfection Kit, as a standalone product?
No, we do not offer this ExpiFectamine CHO Transfection Kit component as a standalone product.
With the ExpiCHO Expression System, can I shake faster or slower than recommended?
We have provided optimal shake speeds for various formats. For most flasks, there is a drop-off in expression when you go too fast or slow because of cell shear stress or insufficient aeration. The effect is sharper in plates where there is a sharper transition between static and moving fluid in wells.
How many days should I wait before harvesting my protein with the ExpiCHO system?
Optimal time to harvest protein will depend on the specific properties of the protein being expressed and the protocol chosen. Typical harvest times to reach maximum titers for the various protocols are as follows:
- Standard Protocol: 8-10 days post-transfection
- High Titer Protocol: 10-12 days post-transfection
- Max Titer Protocol: 12-14 days post-transfection
I didn't add the enhancer with the ExpiCHO system. Will I still get good protein expression?
The Enhancer is designed to work with the ExpiCHO system for maximal expression. If the enhancer is not added, there will be a greater than 50% loss in expression.
