Can I freeze the 96-well Nucleocuvette Plates?

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

Is there a difference between, for example, the programs C-20 and C-020?

No, the programs C-20 and C-020 are identical regarding their electrical parameters. The letter minus a two-digit number is the nomenclature of the Nucleofector™ I. Since we have launched the Nucleofector™ II we changed it to a letter minus a three...

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...

Why do you recommend 7AAD instead of PI staining for cell determination in mouse macrophages?

The results obtained using 7AAD staining are much clearer than those obtained using PI. Using flowcytrometry stained and unstained, transfected and non-transfected populations can be separated much more easily.

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...

How long have you been able to observe GFP expression in primary Human Keratinocytes?

GFP expression has been observed for up to one week as measured by light and fluorescence microscopy.

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.

Is it possible to use different substrates (e.g. siRNA duplexes) with the 96-well Shuttle Device?

Yes. Transfection can be done with any substrate AND under exactly the same conditions. For example, the same conditions (96-well Shuttle™ Solution and program) are used for siRNA transfection or shRNA vectors. This greatly facilitates the...

Do I need a special incubator for cultivation of insect cells ?

Insect cells are cultivated at lower temperatures than E.coli or mammalian cells (S2 cells at 24°C, Sf9 cells at 28°C). Therefore they need a dedicated incubator with appropriate temperature.

What is the advantage of the 96-well Shuttle Device over common lipofection, especially in a high throughput framework?

Several primary cells of high research relevance can simply not be transfected at relevant efficiencies and viabilities using lipofection. The same holds true for many suspension cell lines which are often used for protein production. These...
