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® System 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...

Are there any effects on the differentiation of neural stem cells following Nucleofection®?

The ability of transfected rat or mouse neural stem cells to be subsequently differentiated into a variety of cell types is well documented in:Olig2 Overexpression Induces the In Vitro Differentiation of Neural Stem Cells into Mature...

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.

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 calcium influx issues affect viability or differentiation in Stem Cells after Nucleofection®?

When cells are transfected by Nucleofection®, transient pores are generated in the cell membrane. Generally, these pores disappear within 15 minutes of transfection, but if cells are plated immediately after Nucleofection® in medias that contain...

How can I remove the cells from the 100 uL Nucleocuvette® Vessel after Nucleofection®? Is there any alternative?

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

What is the basic principle of the Nucleofector® Technology?

The Nucleofector® Technology is a novel transfection method especially designed for the needs of primary cells and difficult-to-transfect cell lines. It is a non-viral method based on a unique combination of electrical parameters and cell-type...

Why is the Nucleofector®Technology ideal for primary cells and difficult-to-transfect cell lines?

There are several reasons to choose the Nucleofector® Technology for your gene transfer experiments. One is the direct transfer of DNA to the cell nucleus. This makes gene expression independent from cell division. Therefore, the technique is the...

What optimization is necessary to get the Nucleofector® Technology to work?

None. For each cell type in our product list we offer a cell-type specific solution and thoroughly optimized electrical parameters. These are already pre-programmed in the Nucleofector® Device. Additionally our optimized protocols give you...

Is your pmaxGFP control vector supplied with the Nucleofector® Kits suitable for stable expression?

No. This vector is only supplied in our Nucleofector® Kits as a positive control and cannot be used for selection because it does not contain a mammalian selection marker. The only resistance gene expressed by this vector is kanamycin which is...
