Can I use the settings recommended for the Nucleofector® I/II or 2b System with my 4D-Nucleofector® System?

No, the 4D-Nucleofector® is optimized for conductive polymer electrodes, while the Nucleofector® I/II or 2b System is working with electrodes made of aluminium.We recommend doing a quick cell line optimization using our Cell Line...

What age are the mice and rats that your Clonetics Mouse and Rat Astrocytes are isolated from?

They are embryonic. The rats are E18 or E19 and the mice are E14 or E15.

Can I reuse the 100µl Nucleocuvette® Vessel?

We do not recommend reusing the conductive polymer cuvettes as performance decreases when cuvettes are used more than once.


I transfected neurons using the 4D-Nucleofector® Y unit. During analysis I observed areas with low or no cell density, even in my no pulse control sample.

Cells might have been disturbed or ran dry during pipetting steps. Please perform liquid removal and additions well-by-well. Avoid leaving neurons without any liquid coverage (medium or Nucleofector® Solution). To keep a small liquid film on the...

How many cells do I have to use for each well of the 16-well Nucleocuvette® Strip?

This depends on the cell type you are working with. In our Optimized Protocols the cell numbers range from 2.5 x 10^4 cells (mouse DC) up to 1x 10^6 cells (human T cells). Detailed information is provided in our 4D-Nucleofector® Optimized Protocols.


Do I have to apply the same program to each well of the 16-well Nucleocuvette®?

No, each well can be addressed separately. You may apply up to 16 different programs to one 16-well Nucleocuvette® Strip.

I would like to use the dipping electrode array for less than 24 wells. How can I keep non-required dipping electrodes clean?

We would recommend to prepare the culture plate as such that cells are only plated into those wells that should be transfected and leave further wells empty.After withdrawing the dipping electrode array from the plate you can wipe off residual liquid...

Do the Clonetics Rat and Mouse Astrocytes require an extracellular matrix for plating?

No, they simply need to be seeded onto tissue culture treated plastic. For best performance, we recommend to use positively charged plasticware
