Get Higher Transfection Efficiency
Xfect is a biodegradable transfection polymer, screened from a pool of 2,300 candidates for its very high transfection efficiency and low cytotoxicity profile. Xfect provides excellent transfection for most cell types:
- HeLa cells typically transfect with 85–90% efficiency
- 293-based cells typically transfect with 95–99% efficiency
High efficiency transfection of seven commonly-used cell lines using the Xfect Transfection Reagent.
More of Your Transfected Cells Are Viable!
An obvious way to increase transfection efficiency is to increase the amount of DNA/transfection reagent mixture that you add to your cells. Unfortunately, since most transfection reagents damage cells during transfection, transfecting more DNA to increase efficiency is not an option. Xfect, however, creates non-toxic biodegradable nanoparticles with DNA so you can add more of the transfection mixture to your cells to get more transfected cells that are also viable.
Xfect transfection reagent yields higher numbers of viable transfected than the most popular competitor reagent. Xfect and Product L were each used according to their respective protocols to transfect HeLa cells with increasing amounts of pAcGFP1-C1 plasmid. 48 hr posttransfection, transfection efficiency was determined by flow cytometry and cell viability was assessed by trypan dye exclusion assay. The percentage of transfected, viable cells was determined.
Don’t Just Take Our Word for it: Customer Success Stories
Our lab transfects a variety of cell lines and was having problems transfecting plasmid DNA into several difficult to transfect cell lines, such as MRC-5 cells. With Clontech’s Xfect Transfection reagent we have seen significantly better results in our MRC-5 transfections. As a bonus, our routine transfections in HEK293, BHK-21, and other cell lines have also significantly improved. We recommend Xfect to anyone searching for a more reliable transfection reagent that also is free from concerns about using special media and concerns about plastics used for setting about up transfection complexes. Clontech is a lifesaver!
I have been doing research with primary rat cardiomyocytes for more than seven years, and plasmid transfection (of these cells) is not easy. I previously believed that the best method was using Lipofectamine 2000 with Plus Reagent and an overnight incubation with Opti-MEM.
Xfect was better than this Lipofectamine method… I was surprised (shocked!)
We will switch to Xfect. High efficiency, no toxicity(!), easy procedure, and low cost.
Thank you for providing such a nice product. I want to tell this to everyone engaging in myocyte biology.
Simple, Serum-Compatible Protocol
For ease of use and happier cells, plasmid transfections can be carried out entirely in the presence of serum. The Xfect transfection protocol requires few steps and minimal optimization—and there’s no need to mess around with ratios! The Xfect reagent kit includes everything you need—no Opti-MEM is required.
