Designed for commonly used and hard-to-transfect cell lines, the reagents offer high efficiency, reproducibility and cell survival rates, compared to transfection reagents, to deliver more viable cells and help accelerate research efforts, Roche said.

Both reagents support a wide variety of cellular and molecular research applications, such as gene expression analysis and protein production.

The X-tremeGENE 9 reagent offers efficient performance across a wide variety of cell lines while X-tremeGENE HP reagent is well suited for cell lines that are difficult to transfect or not easily transfected with other reagents.

The reagents also offer easy-to-implement protocols and researchers simply dilute the reagent, incubate it with plasmid DNA, and pipette it directly onto cells, enabling them to spend less time optimising the reagent and more time advancing their research.

Roche added that both reagents function well in the presence or absence of serum and remain stable after repeated vial openings, helping to save researchers time and effort.
