Suitable for in vivo delivery of DNA, siRNA, miRNA, oligonucleotides and mRNA

in vivo-jetPEI®-Gal is the reagent of choice to deliver any type of nucleic acid to mediate gene expression or gene silencing in various tissues, with enhanced targeting to liver.
in vivo-jetPEI®-Gal is very versatile as it is suitable for the delivery of plasmid DNA, siRNA, shRNA, miRNA, oligonucleotides and mRNA.

Easy two-step protocol

in vivo-jetPEI®-Gal 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®-Gal complexes formed into animal (Fig. 1 ).

Suitable for any animal model

in vivo-jetPEI®-Gal is ideal for nucleic acid delivery in mice. However, the protocol is so easy and versatile that it can be adapted to other species including rat.
Our delivery experts are available to adapt our protocol to your animal model and provide you with starting conditions for your application (Please contact the technical support team at support@polyplus-transfection.com).

Safe: no inflammatory response induced

in vivo-jetPEI®-Gal offers a reliable and safe alternative to viral vectors as it does not induce any significant inflammatory response.

Polyplus-transfection® is ISO 9001 Quality Management System accredited since 2002; this level of certification assures global customers that the supplier has established reliable and effective processes for product development, manufacturing, sales and customer support.

Each lot of in vivo-jetPEI®-Gal is validated by DNA (pCMV-Luciferase) delivery into mouse through intravenous injection. The amount of luciferase (ng) per mg of protein is indicated on the certificate of analysis for each lot of reagent. Moreover, absence of endotoxin is verified in every lot of in vivo-jetPEI®-Gal.
