Systemic delivery (Tail vein, intravenous, intraperitoneal injection)
|Number of transfections|
100 µl of in vivo-jetPEI® delivery reagent is sufficient to perform 15 to 25 intravenous injections in mouse.
-20 °C, for at least 12 months
10% glucose solution
in vivo-jetPEI® is a powerful polymer based reagent used to deliver any nucleic acid to any animal model. The protocol is similar to a classical transfection: the nucleic acid and the reagent are just mixed and administered to the animal.
in vivo-jetPEI® forms stable complexes with the nucleic acid, protecting it from degradation and thus facilitating in vivo delivery.
With a proven track record (over 200 Publications), in vivo-jetPEI® has already been used to target a wide range of organs using various administration routes.
|Catalog Number||Amount of reagent||Amount of 10% glucose solution|

|201-50G||0.5 ml||2 x 10 ml|
Suitable for in vivo delivery of DNA, siRNA, miRNA, oligonucleotides and mRNA
in vivo-jetPEI® is the reagent of choice to deliver any type of nucleic acid to mediate gene expression or gene silencing in various tissues. The success of this delivery system relies on its ability to efficiently deliver the appropriate therapeutic nucleic acid into the target tissue or cells with low toxicity and limited immune response.
in vivo-jetPEI® is very versatile as it is suitable for the delivery of plasmid DNA (Fig. 1), siRNA (Fig. 2), shRNA, miRNA, oligonucleotides and mRNA.

Easy two-step protocol
in vivo-jetPEI® is a very easy-to-use delivery reagent. The protocol consists in preparing the nucleic acid and reagent separately in 5% glucose solution, mixing them together and then, after a 15 min incubation time at room temperature, injecting the nucleic acid/ in vivo-jetPEI® complexes formed into animal (Fig. 3). This protocol is suitable for any administration route and any animal model.

Wide range of administration routes to target different organs
The stability of in vivo-jetPEI®/nucleic acid complexes allows the use of numerous routes of administration including systemic or local injection (Fig. 4).
The route of administration largely determines the targeted organ. For example upon intravenous injection, in vivo-jetPEI®-mediated DNA delivery leads to gene expression mainly in the lung but also in the liver, pancreas, spleen, kidney, heart, bladder and artery (Fig. 5).
|Fig. 5: Organs targeted following systemic nucleic acid delivery using in vivo-jetPEI® in mice. pCMVLuc (50 µg) was complexed with in vivo-jetPEI® in 400 µl of 5% glucose solution and injected into the tail vein. 24 h after gene delivery, organs were extracted and luciferase level in each organ was analyzed using a luciferase assay and expressed relative to the amount of total proteins.|
In addition to intravenous injection, in vivo-jetPEI® is also suitable for local delivery routes such as topical application, intracerebral or intra-articular injections, and it is perfect for nucleic acid delivery into subcutaneous tumor models.
Possible targeted organs include lungs, liver, brain, pancreas, spleen, kidney, heart, bladder, skin, retina, artery, etc.

Suitable for any animal model
in vivo-jetPEI® is ideal for nucleic acid delivery in mice. However, the protocol is so easy and versatile that it has been adapted to many other species including rat, guinea pig, hamster, dog, rabbit, monkey, goat, sheep, cow, marmot, chicken, quail, duck, pigeon, gecko, tadpole, shrimp, zebrafish, abalone, snail, leech, mosquito…

Currently used for therapeutics and clinical trials worldwide
in vivo-jetPEI® has been selected as a delivery vector for several drug development programs due to its safety and delivery efficiency. To fulfill all the quality requirements associated to the use of our reagent in Human, Polyplus-transfection® supplies preclinical grade reagents, as well as cGMP grade in vivo-jetPEI® that are currently used in several ongoing preclinical studies and phase I and II clinical trials (Fig. 6).
Safe: no inflammatory response triggered
Following in vivo-jetPEI® -mediated systemic delivery of nucleic acid, there is no induction of major pro-inflammatory cytokines and no increase in sera levels of hepatic enzymes (Bonnet et al. (2008), Pharm Res, 25:2972) (Fig. 6). Hence, in vivo-jetPEI® offers a reliable and safe alternative to viral vectors that can elicit an immune response.
Stability of the nucleic acid/in vivo-jetPEI® complexes
Complexes formed between nucleic acids and in vivo-jetPEI® do not form aggregates over time and thus are stable for at least 24 h at RT, 4 °C and 37 °C (Fig. 8).
With stable complexes, the nucleic acid is protected for longer, thereby allowing the preparation of complexes in advance or the use of osmotic pumps for a continuous delivery.
|Fig. 8: nucleic acid/in vivo-jetPEI® complexes are stable over time. pCMVLuc (40 µg) was complexed with in vivo-jetPEI®. Complexes incubated for 30 min or 24 h at 4 °C were intravenously injected. Bioluminescent imaging of the animals was performed using IVIS100 bioimaging system (Caliper-PerkinElmer) 24 h after injection.|

in vivo functional studies
in vivo-jetPEI® is perfectly suited to study gene function in vivo and provides the easiest method for the validation of in vitro functional studies into animals.
in vivo-jetPEI®-based nucleic acid delivery is now widely used for tumor growth inhibition studies. As an example, the delivery of a modified siRNA against Cyclin B1 with in vivo-jetPEI® inhibits the formation of lung metastases (Fig. 9A) and in vivo-jetPEI® mediated delivery of a modified siRNA against Survivin prevents the growth of a tumor xenograft model (Fig. 9B).
Following in vivo administration of plasmid DNA formulated with in vivo-jetPEI®, the expressed protein can elicit the induction of a robust and persistent immune response, hence protecting animals from different viruses or pathogens challenge.
in vivo gene editing using CRISPR/Cas9 system
in vivo-jetPEI®-mediated delivery of CRISPR/Cas9 system targeting tumor suppressor genes provides a flexible and effective method to investigate somatic loss-of-function alterations and their influence on tumorigenesis.
