8 个常见问题解答

FreeStyle Max试剂相对于293fectin转染试剂的优势是什么？

FreeStyle Max试剂与293fectin转染试剂能够提供水平相近的高转染效率；不过，FreeStyle Max试剂具有更低的细胞毒性，进而能够实现更高的蛋白得率。此外，FreeStyle Max试剂为非动物源性的。  

培养于FreeStyle 293表达培养基中的FreeStyle 293-F细胞能使用ExpiFectamine293试剂和增强剂进行转染吗？如果可以，转染效率会比使用FreeStyle Max试剂更高吗？

您可使用ExpiFectamine293试剂来转染FreeStyle 293表达培养基中培养的FreeStyle 293-F细胞；不过，增强剂只会对蛋白表达提供少许的促进作用，因为这一产品是针对更高密度培养设计的，而FreeStyle 293表达培养基并不适用。 

What is the advantage of FreeStyle Max Reagent over 293fectin Transfection Reagent?

Both FreeStyle Max Reagent and 293fectin Transfection Reagent provide similar levels of high transfection efficiency; however, FreeStyle Max Reagent has lower cytotoxicity and hence results in higher protein yields. Additionally, FreeStyle Max Reagent is animal-origin free.

Can FreeStyle 293-F cells grown in FreeStyle 293 expression medium be transfected with ExpiFectamine293 Reagent along with enhancers? Is so, will the transfection efficiency be higher than that with FreeStyle Max Reagent?

You should be able to use the ExpiFectamine293 Reagent for transfection of Freestyle 293-F cells grown in FreeStyle 293 Expression Medium; however, the enhancers will provide only a little boost in expression as they are designed to work with higher density cultures that FreeStyle 293 Expression Medium cannot support.

What is the recommended ratio of DNA and transfection reagent when transfecting Freestyle cells?

The optimal amount will vary, but we recommend starting with a 1:1 ratio of DNA and lipid. For example, 1.25 ug DNA and 1.25 ul of the reagent for one ml of suspension cells.

How does FreeStyle MAX reagent compare to Lipofectamine 2000 and 293fectin reagents?

Lipofectamine 2000 is designed for adherent cells. FreeStyle and 293fectin reagents are designed for suspended Hek293 and CHO cells. For transfecting 293 suspension cells, FreeStyle MAX reagent yields transfection efficiency comparable to Lipofectamine 2000 and 293fectin reagents. However, Lipofectamine 2000 and 293fectin reagents do not work well for CHO suspension cells.

Can FreeStyle MAX reagent be used for transfecting adherent cells?

Yes, the reagent can be used for adherent cells, however the protocol supplied with the reagent has been optimized for CHO and 293 cells in suspension culture. If you want to transfect adherent cells, please use Lipofectamine 2000 transfection reagent.
