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 cuvette after Nucleofector? Is there any alternative?

We recommend using the plastic pipettes provided in the kits. These pipettes prevent any damage to the cells and ensure a good cell recovery.

Do you have any siRNA Nucleofection results using concentrations lower than 50nM?

Yes. Please click on the attached Technical Reference Guide: "Designing an RNAi Experiment Using Nucleofection™". On page 3 you can find a table with some examples.

The animal facility which isolates my hepatocytes is at a different location, should I be concerned about transport time?

Isolated hepatocytes can be transported in Krebs-Henseleit Buffer or supplemented William's E Medium. Long transport time for isolated hepatocytes, (in excess of one hour) can cause a decrease in efficiency of Nucleofection™, but does not seem to...

How much DNA can I use when transfecting hepatocytes with the standard Nucleofector?

We have used up to 6 µg of DNA per 100 µl reaction with no deleterious effect.

For hepatocytes, is plating density a concern post Nucleofection?

Yes, the optimized protocols for the standard Nucleofector™ recommend the use of 6 well plates. Plating into a 12-well plate will pose a problem as less cells will attach at high densities.

Four hours after Nucleofection, I can see the hepatocytes have attached to the well, but the morphology does not look correct, should I be concerned?

There is no reason for alarm. The hepatocytes may not exhibit normal morphology a few hours after Nucleofection™ but by 24 hours post Nucleofection™, morphology should be normal. Remember to perform a fluid change about 4 hours post Nucleofection™....

What method can I use to fix my HL-60 cells as shown in your optimized protocol?

The cells which are shown in the HL-60 optimized protocol are living cells and not fixed cells. However a good method for fixation of GFP is to use 3.5%-4% Paraformaldehyde in PBS. Please keep in mind that the fixation method is dependant on what...

What are the contents of a 96-well Shuttle Kit?

As the system will most likely be used for high-throughput approaches we provide plates which are pre-equipped with 96-well Nucleocuvette™ modules (2x8). In addition to that, the 96-well Shuttle solution, the supplement, and the pmaxGFP™ are also...

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 non-dividing...
