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...

Which pipette tips are compatible with the 96-well Shuttle Nucleocuvette Plates?

We recommend using special tips, e.g. epT.I.P.S™ (Eppendorf, Hamburg, Germany) or TallTips™ (Matrix Technologies, Hudson, NH, USA). You can contact our Scientific Support Team for a list of compatible tips, including tips for pipetting robots.

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.

Can I freeze the 96-well Nucleocuvette Plates?

Yes. Freezing of the plates at -20°C does not alter their properties.

What is the proof that DNA enters the nucleus during Nucleofection?

There are two facts that prove that the DNA is directly transported into the nucleus: 1.) Using the Nucleofector™ Technology, transfection of non-dividing cells is possible. With conventional non-viral transfection methods cell division is a...

Can I integrate the 96-well Shuttle Device into a liquid handling system?

Yes. The 96-well Shuttle™ Device is designed in such a way that it is addressable by robot grippers. Furthermore, the software contains the required interface to be connected with the LHS software. However, the practical implementation for each...

How can I remove the cells from the cuvette after Nucleofector? Is there any alternative?

We recommend using the plastic pipettes provided in the kits. These pipettes prevent any damage to the cells and ensure a good cell recovery.

Can I use the Nucleofector 2b Solutions and Optimized Protocols with the 4D-Nucleofector X-Unit or the 96-well Shuttle Device?

No. The 4D-Nucleofector and 96-well Shuttle™ System uses specifically optimized electrical parameters and solutions. Five different 4D-Nucleofector or 96-well Shuttle™ Solutions are available for primary cells. For cell lines, three different...

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 method can I use to fix my HL-60 cells as shown in your optimized protocol?

The cells which are shown in the HL-60 optimized protocol are living cells and not fixed cells. However a good method for fixation of GFP is to use 3.5%-4% Paraformaldehyde in PBS. Please keep in mind that the fixation method is dependant on what...
