Transfection of 5. Nucleic acid in vivo - in vivo-jetPEI™

Non-viral gene delivery to animals is easy with in vivo-jetPEI™ transfection reagent. Simply mix your DNA (or siRNA) with this reagent and administer to animals for gene expression in multiple tissues.

With in vivo-jetPEI™, you can also deliver genes by different modes into different species based on your needs (even humans in GMP conditions). You'll avoid experimental and regulatory hassles by choosing in vivo-jetPEI™ in place of virus for gene delivery.

This reagent can be made under GMP conditions and customized to target specific cells.
