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 kind of protocol you recommend for stimulation of human T cells?

For getting the results we present in our datasheet, we recommend the follwing strategy: Cells should be stimulated and cultivated for 3 days before Nucleofection, preferentially on plates coated with 1 µg/ml anti-CD3 and 2 µg/ml anti-CD28 antibody....

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...

My Nucleofector Solution was frozen. Is this a problem?

As long as the supplement was not added to the Nucleofector™ Solution, then there is no risk of any damage to the solutions. Even long-term storage of several months did not alter the performance of the Nucleofector™ Solution. However, if the...

I have a GFP construct that I use and usually get anywhere from 50-80% GFP positive cells using FACS analysis while I get only 30-40% using a GFP-NFAT fusion protein driven by the same promoter. Do you have any suggestions?

The Amaxa™ Nucleofection™ Conditions are optimised for each cell type, the solutions and programs are cell type dependent and not vector dependant. The expression of the fusion protein depends on the localization of the protein transcription,...

Can calcium influx issues affect viability of human Mesenchymal Stem Cells (hMSC)?

Yes. When cells are transfected using 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 media that...

I currently work with some adherent cell lines, such as 293, which are grown in DMEM media. I have noticed that the mortality seems to be high after Nucleofection. Do you have any recommendations?

For some adherent cell lines we strongly recommend using RPMI instead of DMEM medium. As described in culture conditions of the cell line optimization kit protocol as well as the NIH3T3 (DSMZ) protocol, using RPMI instead of DMEM as "transfer and...

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 high...

Can I use the Nucleofector Technology for RNAi applications? How do I start?

Yes. The Nucleofector™ Technology can be easily applied for any RNAi substrate (siRNA, shRNA, miRNA). You can use the same conditions described in the cell type specific Optimized Protocol for DNA vectors (cDNA, shRNA or miRNA expressing plasmids) or...

What are the requirements for direct Nucleofection of mRNA for protein expression?

The mRNA should be capped and polyadenylated. The conditions of Nucleofection™ will be the same as for DNA with the particular cell type, i.e. follow the same protocol and use the same program, except one will likely need to add a much higher amount...
