How should I purify my DNA for Nucleofection® of neurons?

The quality and the concentration of DNA used for Nucleofection® in general plays a central role for the efficiency of gene transfer. We strongly recommend using endotoxin free prepared DNA. Endotoxin free Kits are available from several...

Can I use a Nucleofector® I or Nucleofector® 2b Device together with the 96-well Shuttle® Device?

No, the 96-well Shuttle® only works in conjunction with the Nucleofector® IIs Device or our 4D-Nucleofector® Device.

What is the advantage of the Nucleofector® Technology over common electroporation (systems)?

High cell viability and high transfection efficiency with the Nucleofection® Technology are the most prominent features. Nucleofection®, i.e., the transfer of DNA into the nucleus and not only the cytosol, is essential when working with...

I've noticed that duration of the Nucleofection® Program seems to change even when I haven't changed the program I am using. Why?

The duration time of a program is dependent on the number of the program. The duration is also dependent on how long the Nucleofector® System has been turned on as well as the number of Nucleofections you have done in the last couple of...

What is the molecular weight (MW) of your control plasmid pmaxGFP?

The molecular weight is approximately 2.3x10e6 g/mol based on the average MW of a base pair being 660 g/mol.


What is the lowest amount of DNA which can be used for transfection? Do I need a DNA carrier for low DNA amounts?

The recommended amount of DNA per 100 µl reaction is 0.5µg-5 µg. No carrier is needed.

Is it possible to pre-plate substrates when using the 96-well Shuttle® for Nucleofection®?

Yes, pre-plating of substrates like siRNA and subsequent storage at -20°C is possible.

Can I use larger cuvettes for my Nucleofection Reaction ? Can I use the cuvettes more than once?

No. The electrical parameters provided by the Nucleofector™ Device are optimized for the cuvettes contained in the Nucleofector™ Kits. The cuvettes are single-use only. Using the cuvettes more than once will result in higher cell death and lower...

If I use Miltenyi paramagnetic beads for positive selection of cells, i.e. beads remain on the cell surface, does that influence Nucleofection® results?

No, it seems that the beads bound to the cell surface do not have any influence on Nucleofection®. Larger magnetic beads (i.e. > 1µm) may disturb the Nucleofection® process and negatively influence cell viability and efficiency.
