What kit sizes are available for the 4D-Nucleofector® X Unit?

We offer two different kit sizes for the 100 µl Nucleocuvette® Format (12 and 24 reactions) and one size for the 20 µl 16-well Nucleocuvette® Strip Format (32 reactions). 

What are the best time points for analysis of my siRNA experiments?

As the stability and half-life of various mRNAs and their protein products varies, it is important to empirically determine the best time points for assessing target knockdown. For example, it has been documented that in mammalian cells, mRNA...

What cell numbers can I transfect when using the 4D-Nucleofector® System?

The 4D-Nucleofector® System offers great flexibility in terms of cell numbers.Using the 4D-Nucleofector® X Unit it is possible to perform Nucleofection® in 100 µl and 20 µl Format.The 100 µl Nucleocuvette® Format is suited for high cell...

Can I co-transfect oligonucleotides and plasmids with the Nucleofector® Technology?

Yes. As the same protocol applies for any nucleic acid substrate (vectors or oligonucleotides) you can easily perform co-transfections either for transfection control or rescue experiments.

How many samples can I transfect in parallel when using the 4D-Nucleofector® X Unit?

The 4D-Nucleofector® X Unit offers flexible throughput from 1 to 16 samples. When working with 100 µl single Nucleocuvettes® you can process two vessels in parallel. However subsequent handling of more than 2 vessels is eneased via the option to...

How many different primary cell kits are available for the 4D-Nucleofector® System?

In contrast to the Nucleofector® I, II and 2b System which comes with individual kits for each primary cell type, the 4D-Nucleofector® System only requires 5 primary cell kits covering a broad range of primary cells. There are cell-type...

What is the advantage of using conductive polymer as electrode material for the 4D-Nucleofector® X-Unit and 96-well Unit?

With conductive polymer electrodes the release of metal ions into the cell suspension is avoided. Conductive polymer electrode Nucloecuvette® Vessels are used in the 4D-Nucleofector® X-Unit and 96-well Unit?

Can I use the settings recommended for the Nucleofector® I/II or 2b System with my 4D-Nucleofector® System?

No, the 4D-Nucleofector® is optimized for conductive polymer electrodes, while the Nucleofector® I/II or 2b System is working with electrodes made of aluminium.We recommend doing a quick cell line optimization using our Cell Line...

Why does Lonza recommend using non-ventilated caps when culturing insect cells?

The reason is that insect cells are often incubated in very simple incubators that are not humidified (and without CO2 at 24°C to 28°C). Insect media typically do not need CO2 for buffering pH, so gas exchange is not required. To avoid evaporation of...

Can I reuse the 100µl Nucleocuvette® Vessel?

We do not recommend reusing the conductive polymer cuvettes as performance decreases when cuvettes are used more than once.
