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...

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...

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...

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.

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...

What can I do if there is no Nucleofection® optimized protocol available for my cell of interest?

Lonza is constantly developing new optimized kits and protocols for an increasing number of primary cells and cell lines. In order to obtain the latest information, check our website or contact our Scientific Support Team.We are offering Primary Cell...

Is there a special recommendation on Human T cell enrichment before Nucleofection®?

For Nucleofectio® it is preferable to use Human T cell populations enriched by magnetic separation. For example, MACS™ Microbeads (Miltenyi) or by a rosetting method. For magnetic separation we recommend negative selection or detaching beads...

Are there any recommendations to avoid excessive mortality during T cell Nucleofection®?

Try to keep the DNA amount for Nucleofection® quite low (e.g. 1 µg plasmid DNA per 100 µl reaction) since higher DNA amounts might cause increasing toxicity and mortality. It is also important to use highly purified DNA, e.g. by using Endofree™...
