ScreenFect® Products

Our ScreenFect® transfection reagents are developed using patented combinatorial chemistry methods, which generates chemical libraries. Using these chemical libraries, candidate reagents are identified by high-throughput cell screening approaches. Finally, optimal reagents are further optimized for specific applications. Our ScreenFect® transfection reagents can be used for transfection of nucleic acid molecules (pDNA, siRNA, mRNA, miRNA) as well as co-transfection of combinations of these. 

ScreenFect® reagents provide excellent performance in many standard cell lines as well as difficult-to-transfect primary and stem cells. Examples of cell lines successfully transfected with ScreenFect® reagents can be found here. Currently these reagents are available:
