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...

What is the basic principle of the Nucleofector Technology?

The Nucleofector™ Technology is a novel transfection method especially designed for the needs of primary cells and difficult-to-transfect cell lines. It is a non-viral method based on a unique combination of electrical parameters and cell-type...

Why is the Nucleofector Technology ideal for primary cells and difficult-to-transfect cell lines?

There are several reasons to choose the Nucleofector™ Technology for your gene transfer experiments. One is the direct transfer of DNA to the cell nucleus. This makes gene expression independent from cell division. Therefore, the technique is the...

What optimization is necessary to get the Nucleofector Technology to work?

None. For each cell type in our product list we offer a cell-type specific solution and thoroughly optimized electrical parameters. These are already pre-programmed in the Nucleofector™ Device. Additionally our optimized protocols give you...

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....

What can I do when there is no optimized protocol available for my cell of interest?

"Lonza is constantly developing new optimized kits and protocols for an increasing number of primary cells and cell lines. In order to obtain the latest information, check our website or contact our Scientific Support Team. We are offering Cell Line...

Can Lonza's antibiotics be used in clinical trials?

No. They are for research purposes only.

What is the best way to establish the Nucleofector Technology in my lab?

We strongly recommend establishing the Nucleofector™ Technology with the positive control vector pmaxGFP™ provided in our kits. pmaxGFP encodes the green fluorescent protein (GFP) from Copepod Pontellina sp. Just like eGFP expressing cells, maxGFP™...
