As Transfection Experts, we know that it is essential for biologists to work with physiologically relevant cell models. For gene expression studies, transfection is the preferred technique to introduce a gene of interest in a given cell model, due to its cost-effectiveness and simplicity-of-use in comparison to physical techniques (e.g. micro-injection, electroporation).

Several types of cells (primary cells, stem cells or cancer cell lines) remain difficult to transfect with DNA for different reasons: slow-dividing rates, cell fragility and cellular defense mechanisms. To address the current limits of DNA transfection and complement our existing gene expression portfolio (jetPEI® , jetPRIME® , jetMESSENGER® ), Polyplus-transfection® engineered an innovative delivery nanoparticle: jetOPTIMUS®.

jetOPTIMUS® is a powerful transfection reagent that improves cellular uptake and endosomal escape of DNA in adherent cells (even in hard-to-transfect cells) resulting in higher transfection efficiency. In order to work in relevant physiological conditions, transfection with jetOPTIMUS® requires a minimum DNA quantity and reagent volume to keep an excellent cell viability and morphology.
