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.
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.
Can I use a different transfection reagent with the Expi-CHO Expression System?
The ExpiFectamine CHO Transfection Reagent, ExpiFectamine CHO Enhancer and ExpiCHO Feed are optimized to work together to provide maximal protein expression levels and are provided as a single kit for convenience. The ExpiFectamine CHO Transfection Reagent provides high transfection efficiency of high density cultures, superior to any other transfection reagent. Expression levels greater than 30-fold higher are obtained using the ExpiCHO kit as directed versus substitution of PEI as a transfection reagent, while also using 50% less DNA.
