Dilution Buffer Volume

We limit the amount of supplied ScreenFect® Dilution Buffer to 50 mL per mL of ScreenFect® reagent, thereby preventing unnecessary wastage and shipment weight.

In some situations the amount of ScreenFect® Dilution Buffer may be limiting with respect to the amount of ScreenFect®siRNA or ScreenFect®A-plus reagent, although this is generally not an issue for the vast majority of our customers.

If, however, you require additional Dilution Buffer for your particular transfection experiments then please contact us and we will help you.

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. The following reagents are available:
