The CRISPR/Cas9 engineered nuclease system is a powerful and highly specific genome editing tool. CRISPR/Cas9 is a two component system with a guide RNA (gRNA) molecule that drives the Cas9 nuclease to a specific targeted sequence within the genome in order to introduce genetic modifications (mutations, insertions or deletions).
jetCRISPR™ is an innovative reagent especially designed to deliver RNP in a CRISPR/Cas9 experiment. jetCRISPR™ leads to high CRISPR genome editing efficiency and keep an excellent cell viability and morphology. Use the leading technology for CRISPR/Cas9 RNP delivery!

High Genome Editing efficiency
jetCRISPR™ has been specifically designed for high transfection efficiency of RNP (guide RNA and Cas9 protein complex), thus leading to a high cas9-mediated genome editing efficiency on a wide variety of targets in different cell types (Fig. 1 & 2).
jetCRISPR™ transfection reagent achieves higher genome editing efficiency than other competitors, which makes it the product of choice for CRISPR applications.
Excellent cell viability
At Polyplus-transfection, we are proud to work with reagents that are extremely gentle to cells, maintaining an excellent cell viability and morphology throughout the whole duration of the experiments. jetCRISPR™ is compatible with both serum and antibiotics, hence RNP transfection can be performed in the optimal conditions for healthy cells (Fig. 3).
Fast and Reliable gene editing
Delivering the Cas9 directly as a protein instead as a plasmid allows for faster genome editing as the protein is readily available for use. Using jetCRISPR™ to deliver Cas9 protein and gRNA leads to fast and reliable gene editing (Fig. 4). In addition, the Cas9 protein will be cleared from the cells faster than the plasmid, hence minimizing off-target effects and leading to more specific genome editing (Kim S, et al; Genome Research 2014; 24:1012–1019).
Easy to use
jetCRISPR™ is provided as a ready to use solution. Transfecting RNP is now a very straightforward process only requiring a few steps: form the RNP complexes, add the transfection reagent and add to the wells!
Both reverse and forward transfections are perfectly fine to use with jetCRISPR™, hence allowing you to adapt your protocol to suit the cells that you are working with, the plate format as well as the time of analysis. By using the reverse protocol (Fig. 5), data will be available a day earlier than if you use the forward protocol.
Successful delivery of the gRNA and the Cas9 into cells is indispensable to guarantee the high genome editing efficiency that is required to generate new cell or animal models. While DNA-free delivery systems in which the Cas9 protein is delivered as a protein/gRNA (RNP) have become attractive alternative, as they overcome the main obstacle that DNA entry into the nucleus constitutes, as well as prevent unwanted DNA integration. In addition, delivering the Cas9 protein leads to a better control in Cas9 expression, thereby attenuating off-target Cas9 nuclease activity. This is undoubtedly why scientists need to have a reliable transfection reagent especially designed for this application.
We now provide a full range of reagents for all your CRISPR experiments (Table 1 & Fig. 6):

Every batch of jetCRISPR™ reagent is tested in-house in HEK-293 cells following a reverse protocol in 96-well plates with 30 nM of RNP targeting the HPRT1 gene using 0.3 µL of jetCRISPR™. INDEL (%) is quantified 48 hours post-transfection using the T7 endonuclease assay. Each vial is provided with a Certificate of Analysis.
