In vivo Transfection
|
In vivo Magnetofection™ has been designed for in vivo targeted transfection of various types of nucleic acids such as DNA, RNA, oligonucleotides.
OZ Biosciences offers two types of ready-to-use In vivo Magnetofection™ reagents:
-
In vivo PolyMag is a cationic polymer-based magnetic
nanoparticles formulation. It can be used with plasmid DNA, antisense
oligonucleotides, mRNA, shRNA and siRNA.
-
In vivo DogtorMag is a cationic lipid-based magnetic nanoparticles formulation. It associates Dogtor a specific cationic lipid and CombiMag magnetic nanoparticles.
This reagent is also suitable for plasmid DNA, antisense oligonucleotides, mRNA, shRNA and siRNA.

High efficiency for targeted delivery of DNA
In vivo Magnetofection™ has been used for local gene delivery in blood vessels. Plasmid DNA encoding luciferase complexed with PolyMag magnetic nanoparticles were injected into the ear veins of pig and ear artery of rabbit. A permanent magnet was placed respectively upstream and downstream the blood flow circulation and near the injection sites.
Results demonstrated that transgene was expressed at the magnet position indicating an efficient magnetic targeting.

Fig1: High efficiency of In vivo PolyMag for targeted gene delivery after intravenous injection.
After 42h, reporter gene expression was found primarily at the magnet position site and to a lesser extent proximal and distal of the magnet. As control, the same vector composition was injected in the contralateral vessel without application of a magnet. No significant reporter gene expression was found at the topographically analogous positions.

High efficiency for DNA delivery in
hard-to-transfect tissue
Gene delivery and gene therapy in the guts are particular challenging due to the abundance of degradative enzymes, the presence of degraded nutriments and bacteria. In their study, Scherer and coll. successfully transfect a plasmid DNA encoding Lac-Z gene complexed with PolyMag magnetic nanoparticles into guts. Complexes were injected into the ileum lumen of rat and a permanent magnet was applied for 20 minutes.

Transfection in rat intestine
|
|
Complexes of DNA and PolyMag nanoparticles were applied to the ilea of rats in absence (A) or under the influence of a magnetic field (B). X-Gal staining was performed after 48h and revealed an efficient gene delivery only in the presence of magnet (B) at the macroscopic level (upper panel) and at the microscopic level (lower panel). In absence of magnetic field, only rare transfection events were observed (A). From Scherer et al., Gene Therapy., 2002; 9:102-109.
