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 difference between reverse transfection and forward transfection? What should I use?
In forward transfection, cells are seeded to appropriate confluence or cell density in wells or dishes, and the lipid-DNA complexes are added the next day. In reverse transfection, the transfection complexes are prepared inside the wells, after which cells and medium are added. Reverse transfection is faster to perform than forward transfection, and is the method of choice for high-throughput transfection. For non-high-throughput transfections, generally forward transfections have better efficiency for most cell types.

Is there a place where I can find references from other researchers who have used your transfection reagents?
Visit the product page for each reagent type and you will see a list of references at the bottom of the page. A table that lists specific cell line references is also accessible. We also recommend www.highwire.org as a search engine to find a large selection of up-to-date research articles using our transfection products. Simply include the name of the transfection reagent and your cell line/application of interest in your search criteria.
