  3. Transduction tools:for producing, concentrating, storing and enhancing virus efficiency.
  4. 3D transfection: allowing nucleic acid delivery directly into 3D matrix.
  5. Protein delivery systems: including antibody & based on biodegradable lipid nanoparticles.
  6. Cell specific reagents: For specific cells such as neurons and stem cells.
  7. Vaccine Adjuvants: Standard & novel adjuvants for antigenic & genetic immunization
  8. mRNAs for transfection: gene reporters, genome editing and vaccine control mRNAs.



Magnetofection™ is a simple and highly efficient transfection method to transfect primary cells and hard to transfect cells.

Magnetofection™ principle is to associate nucleic acids, transfection reagents or viruses with specific magnetic nanoparticles. The resulting molecular complexes are then concentrated and transported into cells supported by an appropriate magnetic field. In this way, the exploitation of a magnetic force exerted upon gene vectors allows a very rapid concentration of the entire applied vector dose on cells, so that 100% of the cells get in contact with a significant vector dose, and promotes cellular uptake.


Magnetofection™ is the only versatile and universal technology adapted to all types of nucleic acids (DNA, siRNA, dsRNA, shRNA, mRNA, ODN), non viral transfection systems (transfection reagents) and viruses. Consequently, several optimized reagents have been designed according to defined

  • Mag4C-LV / Mag4C-AD Kits: for capturing and concentrating Lentiviruses and Adenoviruses
  • FluoMag Transfection reagent: Fluorescent Magnetofection Reagents
  • SelfMag Transfection Kit : for creating your own magnetic delivery system



Lipofection is a lipid-based transfection technology which belongs to biochemical methods including also polymers, DEAE dextran and calcium phosphate.

Lipofection principle is to associate nucleic acids with cationic lipid formulation. The resulting molecular complexes, known as lipoplexes, are then taken up by the cells.


Transfection efficiency combined with high transgene expression level or high gene silencing and minimized cytotoxicity depends on multiple critical parameters. Those factors include cell type, plasmid DNA characteristics (size, promoter, reporter gene) & purity, siRNA sequence & purity, cell culture conditions (medium with or without serum, cell number, absence of contaminations), amount of nucleic acids and reagents, transgene assays to name a few. Consequently, transfection reagents need to be specifically designed according to the nucleic acids to be delivered (DNA, siRNA, mRNA, ODN, shRNA etc.) and the cell types used in order to achieve optimal efficiency. In this context, OZ Biosciences has developed several outstanding transfection reagents:

  • DreamFect™ Gold Transfection reagent: for all nucleic acids, achieving superior transgene expression level
  • DreamFect™ Transfection reagent: for all nucleic acids, for all cells including suspension cell lines

Vaccine Adjuvants

VaxOZ adjuvants are perfect as gold standard references and for any immunization experiment, they can also be customized with your own immunostimulant.

In vivo grade manufactured and quality controlled, the VaxOZ adjuvants are intended for research purposes only.

mRNA Transfection

The use of mRNA over pDNA in transfection has several advantages

  • No need for nuclear uptake - protein expression directly in the cytoplasm.
  • Faster protein expression than DNA transfection.
  • No genomic integration.
  • Perfect for transfecting slowing or non-dividing cells.
  • Protein expression in a total promoter-independent manner.
  • Transient transfection: mRNA based expression of proteins sustains for a limited time.

Oz Biosciences offers three categories of mRNAs that mimic fully processed mature mRNAs:
