Can I order any of the Nucleofector Kit components separately?

No. The Nucleofector™ Kits are only available as full kits.

Who is the distributor for my country?

Please click on the link provided to search for your distributor.

How can I determine the correct centrifugation speed for my particular centrifuge and rotor?

The correct rotor speed can be calculated by measuring the maximum radius of your rotor and entering the information into the table found on the website which can be reached by clicking on the Related Link.

Is the age of the mice important for my mouse T cell Nucleofection?

Yes. We recommend using mice between 6-12 weeks. Using mouse T cells isolated from younger or older animals for Nucleofection™ may result in much lower transfection efficiencies and/or viabilities.

Does the recovery medium contained in the Mouse T Cell Nucleofector Kits contain any immunogenic substances?

No. The post Nucleofection™ Recovery media contains no immunogenic factors and should not influence cell stimulation or differentiation. For Mouse T cells, some experiments have shown that after Nucleofection™ cells can be stimulated efficiently in...

I see activation of my monocytes (or macrophages or DCs) following Nucleofection. Why is this? What can I do to address this problem?

We have examined the effects of Nucleofection™ (without DNA) on these cells and have not observed significant activation. This indicates that neither the Nucleofector™ Solution, the Nucleofector™ Program nor the recovery medium are sufficient for...

I observed high mortality rates in mES cells after Nucleofection with a Cre recombinase expression vector. How can I increase the viability?

The High mortality after transfection might be due to the Cre recombinase itself, because the mammalian genome contains pseudo loxP sites (Thyagarajan B et al. (2000) Mammalian genomes contain active recombinase recognition sites. Gene....

Can Lonza's antibiotics be used in clinical trials?

No. They are for research purposes only.

Why do you have different Optimized Protocols for the Nucleofection of unstimulated and stimulated Human T cells?

We found that the stimulation of T cells not only changes the cells' function but also significantly alters the requirements for successful Nucleofection™. That's why Lonza developed two Optimized Protocols for transfection giving different...

Are your Nucleofector Solutions checked for RNase activity during your QC process?

Yes. We do test the Solutions with a real time RT-PCR based assay. This assay basically measures the quantity of an RNA template after incubation in our solution. In case there is RNAse contamination the template would be digested which would be...
