Polyvalent: in vivo delivery of any nucleic acid in any animal model including mice
The easiness of use and versatility of in vivo-jetPEI® allows scientists to perform gene function studies by overexpressing or downregulating a gene in any organ/tissue of interest. in vivo-jetPEI® is polyvalent: it is suitable for the delivery of any type of nucleic acid (plasmid DNA, siRNA, shRNA, miRNA, oligonucleotides and mRNA) in any animal model (mice, rat, guinea pig, dog, rabbit, monkey, etc…). Numerous Scientific publications demonstrate the successful delivery of each type of nucleic acid in different animal model.
in vivo-jetPEI® has already been used to target a wide range of organs by systemic and local injection routes. Local administration routes include subcutaneous tumor, intracerebral or intra-articular injections and topical application. The injection route largely determines the targeted organs. 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. Conversely, upon intraperitoneal injection, the gene of interest will be expressed in the ovary, pancreas, diaphragm, uterus and stomach (Fig. 1). To achieve organ specific gene expression, cell-specific promoters can be combined with the choice of a local injection route to restrict gene expression to an organ/tissue. Guidelines for systemic and most local injection routes are available.
Easy-to-use: two-step protocol
in vivo-jetPEI® is the reagent of choice to deliver any type of nucleic acid using most systemic and local injection routes. The protocol is easy to use and similar to a classical in vitro transfection: the nucleic acid and in vivo-jetPEI® reagent are mixed and directly injected into the animal model (Fig. 2).
Our delivery experts are available to adapt your protocol to your animal model and send you the relevant literature.
Renowned: Most advanced in vivo delivery technology for cancer research, immunization and vaccination
in vivo-jetPEI® is a powerful polymer-based reagent with unique properties. In the provided complexation solution, in vivo-jetPEI® condenses any nucleic acid into stable nanoparticles of ca. 50 nm diameter (Fig 1). These nanoparticles are sufficiently small to efficiently diffuse within tissues and enter cells by endocytosis, while protecting naked nucleic acids from degradation. At the cellular level, in vivo-jetPEI facilitates both endosomal escape using the proton sponge mechanism (Akinc et al. (2005), J Gene Med 7: 657), and crossing of the nuclear membrane (Brunner et al. (2002), Mol Ther 5: 80).
Successful: Used from fundamental research to Human clinical trials
Due to its reliability, in vivo-jetPEI® has been selected as a delivery vector for several drug development programs due to its safety and delivery efficiency. There are currently several ongoing clinical trials for cancer therapies, vaccination and immunization using higher quality grade GMP in vivo-jetPEI®.
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. 4A) and in vivo-jetPEI® mediated delivery of a modified siRNA against Survivin prevents the growth of a tumor xenograft model (Fig. 4B).
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.
in vivo-jetPEI® is the leading in vivo delivery method with a proven track record of peer-reviewed scientific publications, ranging from fundamental gene function studies to cancer research and vaccination studies. Here is a list of recent publications per application:
