Magnetofection™

Description

Magnetofection™ is a novel, simple and highly efficient method to transfect cells in culture. It exploits magnetic force exerted upon gene vectors associated with magnetic particles to draw the vectors towards, possibly even into, the target cells. In this manner, the full vector dose applied gets concentrated on the cells within a few minutes so that 100% of the cells get in contact with a significant vector dose. This has several important consequences:

  • Greatly improved transfection rates in terms of percentage of cells transfected compared to standard transfection.
  • Up to several thousand fold increased levels of transgene expression compared to standard transfections upon short-term incubation.
  • High transfection rates and transgene expression levels are achievable with extremely low vector doses, which allows to save expensive transfection reagents.
  • Extremely short process time. A few minutes of incubation of cells with gene vectors are sufficient to generate high transfection efficiency, compared to several hours with standard procedures.
Magnetofection principle

Technology

Magnetofection™ Reagents

As the manufacturer of the Magnetofection™ technology, chemicell offers two types of ready-to-use Magnetofection™ reagents.

PolyMAG is a universally applicable magnetic particle preparation for high efficiency nucleic acid delivery. It is mixed in a one-step procedure with the nucleic acid to be transfected and has been used successfully with plasmid DNA, antisense oligonucleotides and siRNAs.

CombiMAG is a magnetic particle preparation designed to be combined with any commercially available transfection reagent such as polycations and lipids and can be associated with plasmid DNA, antisense oligonucleotides, siRNAs or viruses. It allows you to create your own magnetic gene vector based on your favourite transfection reagent.

Nucleic Acids Dose Response and Transfection Kinetics

Transfection kinetics: NIH 3T3 cells were incubated with GenePorter™ (Gene Therapy Systems) ± CombiMAG with and without positioning on the MagnetoFACTOR plate for the indicated time spans. Luciferase expression was assayed after 24 hours.

Applications

Magnetofection™ is generally applicable for adherent cells and has been tested with a variety of immortalized cell lines and primary cells listed below. If a particular cell type or cell line is not listed this does not mean that Magnetofection™ would not work. Also for the cells listed, some reagents have not been tested so far, as indicated by "n.d." (not determined).

The CombiMAG reagent can be combined with any polycationic and lipidic transfection reagent, and also with adenoviral and retroviral vectors. In some cases, references are made in the footnotes to very successful combinations with commercially available reagents that have been tested so far.

MagnetoFACTOR-24 plate

The MagnetoFACTOR-96 plate its special geometry not only produces strong magnetic fields under each well of 96-well plates but is also applicable for other plate formats T-75 culture flasks, 6- and 12-well plates. In the larger plate formats, the MagnetoFACTOR plate will produce a pattern of higher and lower densities of transfected cells according to the geometry of the magnetic field lines. The MagnetoFACTOR-24 plate is special designed for the 24-well format.
