Can I freeze the 96-well Nucleocuvette® Plates?

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

Do you recommend positive selection or depletion for the purification of Human monocytes for Nucleofection®?

We only recommend the depletion method. For Example, the RosetteSep™ Isolation Kit for human monocytes [Stem Cell Technologies, Cat. No 15028]. The advantage of depletion is that the monocytes are left untouched by antibodies during the process.

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...

Does it matter if the PBS used for monocyte enrichment contains calcium and magnesium, if the cells should be used later in Nucleofection®?

The PBS should be calcium and magnesium free to prevent clumping of cells. We routinely use PBS without calcium and magnesium for example Lonza Cat. No. BEBP17-516Q

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

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...

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 is the advantage of the Nucleofector® Technology over common electroporation (systems)?

High cell viability and high transfection efficiency with the Nucleofection® Technology are the most prominent features. Nucleofection®, i.e., the transfer of DNA into the nucleus and not only the cytosol, is essential when working with...

Is the age of the mice important for my mouse T cell Nucleofection®?

Yes. We recommend using mice between 6-12 weeks. Using mouse T cells isolated from younger or older animals for Nucleofection® may result in much lower transfection efficiencies and/or viabilities.

Is it possible to pre-plate substrates when using the 96-well Shuttle® for Nucleofection®?

Yes, pre-plating of substrates like siRNA and subsequent storage at -20°C is possible.

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...
