OZ Biosciences announces the launch of a new range of Magnetofection™ In Vivo reagents

May 18, 2012 - PRLog -- OZ Biosciences SAS, specialized in the development of innovative transfection technologies, further expands their comprehensive catalog with a new product line dedicated to In Vivo transfection  and/infection. These new specialized magnetic nanoparticles-based reagents allow successful nucleic acids delivery in vivo.

The main problems currently associated with systemic gene vector administration (gene therapy) include biodistribution of gene vector throughout the body, lack of specificity towards a pathological site (bioavailability at the target site), non-specific toxicity, inactivation of vectors due to undesired interactions with components of the in vivo milieu and other side effects due to high vector doses.

Magnetofection™ resolves the problems related to diffusion limited process and to restricted bioavailability at the target site.
In vivo Magnetofection™ reagents have been designed for in vivo targeted transfection and infection. This original system combines magnetic nanoparticles and nucleic acid vectors that will be confined after injection at the magnetically targeted site.
“In this way, targeted delivery minimizes systemic distribution and reduces toxicity,” explains Olivier Zelphati, CEO of OZ Biosciences. “Furthermore, the magnetic force will enhance the uptake of magnetic nanoparticles by the target tissue, and thus improve the efficiency of transfection or/ transduction. This allows reducing the required nucleic acid doses and the process time of delivery which is crucial for improvement of in vivo nucleic acid delivery.”
Gene vectors /nanoparticles complexes can be easily administrated through various injection routes such as systemic administration (intravenous, intra-artery) or local administration  (intraperitoneal, intratumoral, intracerebroventricular, intramuscular ).

OZ Biosciences offers three types of ready-to-use In vivo Magnetofection™ reagents:
-   Non viral applications: In vivo PolyMag, a cationic polymer-based magnetic nanoparticles formulation, and In vivo DogtorMag, a cationic lipid-based magnetic nanoparticles formulation, have been designed for in vivo targeted transfection of various types of nucleic acids such as DNA, RNA and oligonucleotides.
-   Viral applications: In vivo ViroMag is an optimized nanoparticles formulation dedicated to viral vectors that allows reduction of titer virus. It is particularly suitable for Lentiviral/Retroviral, Adenoviral and Adeno-Associated Viral (AAV) vectors.
