Superior transfection efficiency

jetPRIME® is a powerful transfection reagent for day-to-day experiments. It leads to unusually high percentage of transfected adherent cell lines of various origins as well as primary cells.

Superior transfection efficiencies ranging between 70 and 90% were obtained with jetPRIME® reagent versus the top competitor’s reagent for several commonly used cell lines (Fig.1).

Fig. 1: Comparative transfection efficiency of jetPRIME versus its main competitor. Transfection efficiency was assessed by FACS analysis in various cell lines 24 h after transfection in 24-well plates. Conditions used were according to the manufacturer’s recommendation for L2K (0.8-1 µg plasmid DNA + 1.6-2 µl reagent per well) and for jetPRIME® (0.5 µg plasmid DNA + 1 µl reagent per well).

Cost-effective: less DNA and less reagent

jetPRIME® is a powerful in vitro transfection reagent that requires a small amount of reagent and plasmid DNA, making its use very cost-effective (Table 1).

In addition to reducing costs, using less DNA also minimizes adverse cytotoxic effects triggered by transfection. Hence, jetPRIME® is the reagent of choice for high transfection efficiency with excellent cell viability.

Better cell viability

jetPRIME® is extremely gentle on cells during transfection leading to increased cell viability and improved transfection results. Cells transfected with jetPRIME® are healthy, while major cytotoxicity is observed with competitors (Fig.2).

Easy to use protocol

jetPRIME® is an easy-to-use transfection reagent :

  • Fast and easy to scale up and down
  • Compatible with serum and antibiotics

Plasmid transfection

jetPRIME® leads to remarkably high percentages of transfected adherent cell lines of various origin, as well as primary cells (Table 1).

Plasmids are small circular DNA molecules that are commonly found in bacteria. Plasmids exist and replicate separately from chromosomal DNA and in bacteria they often carry genes that are beneficial for bacterial survival. Plasmids can be deliberately introduced into desired cells and utilized to overexpress a gene of interest in a specific cell line. This procedure is called DNA transfection and is a commonly used method for studying gene function or protein of interest.

Genome editing

The use of the CRISPR/Cas9 system in mammalian cells has recently emerged as a very convenient way to modify the cell genome at a specific locus. It involves transient transfection into mammalian cells of either (a) one or several plasmids coding for Cas9, the specific gRNA and eventually the sequence to be inserted, or (b) a mix of one or two plasmids and an RNA molecule (the gRNA).

Available application note: CRISPR/Cas9-mediated gene disruption using jetPRIME®.

Virus production

jetPRIME® transfection reagent is highly effective for routine virus production of both AAV and lentivirus in adherent cells grown in classical media such as DMEM in presence of serum.

siRNA transfection

jetPRIME® leads to over 90% knockdown of endogenous gene expression in a variety of cell lines. For example, jetPRIME®-mediated transfection of HeLa cells with 10 nM siRNA duplexes targeting endogenous lamin A/C in HeLa cells drastically reduces lamin A/C gene expression to barely detectable level (Fig. 1).

Co-transfection of different nucleic acids

jetPRIME® is well suited for DNA and siRNA/ miRNA co-transfection experiments or co-delivery of several DNA plasmids.

We performed DNA and siRNA delivery with jetPRIME® and observed highly efficient gene silencing in a variety of cell lines with very low toxicity. Over 90% silencing is achieved in adherent cells, using 10 nM siRNA (Fig. 2).

“jetPRIME gave better transfection efficiencies than other reagents tested and much less cell death was noticed.  The cells don’t seem to mind being treated with the transfection reagent, there is no need to change the media anyway.  I’ve already ordered a bigger volume of jetPRIME and have used half of it already! Will possibly be ordering some more soon!”

Kimberley S, Royal Veterinary College, UK


“I already ordered jetPRIME. It was very efficient and easy to use! Also the cells were in a good state after transfection. Good product!”

Cosima R, University Hospital Erlangen, DE


“Very good transfection efficiency, better value and ease of use”

Sean H. MD Anderson Cancer Center, USA


“jetPRIME has low toxicity and with less amount of DNA and the transfection reagent comparable expression can be achieved. I would prefer using jetPRIME over other reagents for the above mentioned reasons.”
