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...

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.

How many cortical neurons can I expect from a single pup?

According to QBM Cell Sciences, you can expect 12 million cortical neurons from an average E18-E19 rat pup. You can expect 4 million cortical neurons from an average mouse pup.

In my Nucleofection Experiment I see lower expression with my IRES construct in comparison with you pmax-GFP control. Do you have any information about the different expression profiles?

The original attenuation of the IRES sequence was performed to allow for a greater difference between the expression levels of the upstream gene of interest and the downstream reporter gene. If the downstream reporter gene, the product of less than...

Does the 96-well Shuttle recognize if the cuvette plate is in backwards?

No, it does not recognize the orientation of the plate. Please make sure that well A1 is positioned in the upper left corner of the retainer.

Do any of the three instruments used in the 96-well Shuttle System "go to sleep" or power off automatically?

The energy options of the laptop are set as such that only the screensaver is activated, the harddisk won't turn down and hibernation is disabled. One can change these settings via the system control. However this is not recommended because by...

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 is the molecular weight of your control pmaxGFP plasmid?

The molecular weight is approximately 2.3x10e6 g/mol based on the average MW of a base pair being 660 g/mol.

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.
