Do you have a protocol for the Nucleofection of Plasmodium yoelii?

Yes. You can use our new Basic Parasite Nucleofector™ Starter kit for parasitic protozoa. The Basic Parasite Nucleofector Starter Kit (Cat.No. VMI-1001) should help you to determine the optimal program and Nucleofector Solution for your...

How many stable clones will I get from one transfection?

This depends on the respective cell type (transfection efficiency, viability and integration frequency). If it is important to you to know the frequency of stable integrants before carrying out your actual experiments, the frequency should be...

Can I use the pmaxGFP control plasmid with insect cells such as S2 cells or SF9 cells?

The pmaxGFP™ Vector provided in our Nucleofector™ Kits is not expressed in insect cells. We strongly recommend an insect expression vector encoding a fluorescent protein or lacZ reporter as a positive control for your experiments [e.g. Novagen™’s...

Following Nucleofection, I cannot obtain stable clones from single cells, what could be the reason?

Some cell lines need certain cell densities to proliferate. For those cells you can try using conditioned medium for setting up limiting dilution or culturing single cells together with feeder cells.

Do you have a protocol for Nucleofection of parasites?

Yes. You can use our Basic Parasite Nucleofector™ Starter kit for parasitic protozoa. The Basic Parasite Nucleofector Starter Kit (Cat.No. VMI-1001) should help you to determine the optimal program and Nucleofector Solution for your...

Do you have any information regarding differentiation of mouse ES cells after Nucleofection with large plasmids?

It is unlikely that plasmid size would affect in vitro differentiation capability. Gene targeting constructs are often as large as 20 kb and if treated well the ES cells are perfectly capable of generating germ line chimaeras afterwards (indicating...


How much DNA should I use in my Nucleofection Reaction to obtain stable clones?

You should use the amount of DNA recommended in the optimized protocol for transient transfection. If obtaining a very high number of clones is important for your experiments, you can try increasing the amount of DNA. For further tips see our...

Does the Mouse T cell protocol work for stimulated mouse T cells?

Yes. Stimulate the cells with anti CD3 and anti CD28 antibody for 24 hours. Use the optimized protocol. Often times, this will result in higher transfection efficiency (60-70% is possible). Alternatively, you can stimulate with ConA and IL-2 for 2-3...

What are the benefits of Amaxa Nucleofection over standard electroporation?

One major benefit of the Nucleofector™ Technology is that the nucleic acids are transferred directly into the nucleus enabling the transfection of non-dividing cells and an early analysis of transgene expression (depending on the protein) in as...
