Can I use the Nucleofector™ Technology for RNAi applications? How do I start?

Yes. The Nucleofector™ Technology can be easily applied for any RNAi substrate (siRNA, shRNA, miRNA). You can use the same conditions described in the cell type specific Optimized Protocol for DNA vectors (cDNA, shRNA or miRNA expressing plasmids) or...

Do you recommend positive selection or depletion for the purification of Human monocytes for Nucleofection™?

We only recommend the depletion method. For Example, the RosetteSep™ Isolation Kit for human monocytes [Stem Cell Technologies, Cat. No 15028]. The advantage of depletion is that the monocytes are left untouched by antibodies during the process.

Can I order any of the Nucleofector™ Kit components separately?

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

Does it matter if the PBS used for monocyte enrichment contains calcium and magnesium, if the cells should be used later in Nucleofection™ ?

The PBS should be calcium and magnesium free to prevent clumping of cells. We routinely use PBS without calcium and magnesium for example Lonza Cat. No. 17-516F

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...

Is it possible to use frozen primary CD34+ hematopoietic stem cells for Nucleofection™?

Yes. For cryopreserved PBMCs or enriched CD34 populations, we recommend culturing the thawed cells 1-2 hours in culture medium before Nucleofection™. Any further enrichment procedure after thawing is not recommended. Viability of frozen nucleofected...

What are the critical steps for successful Nucleofection™ of monocytic cell lines like THP-1, HL60 and U937?

To achieve optimal results, we strongly recommend following the Optimized Protocols in regard to cell culture conditions (medium, splitting cycle, density before Nucleofection),DNA amount and purity. Please also be sure not to exceed 90xg when...

Do you recommend a particular supplier for siRNA duplexes for use in Nucleofection™ ?

For siRNA applications using the Nucleofector technology we recommend siRNA duplexes from Dharmacon, part of Thermo Fischer Scientific.

Can I use the protocol for MCF7 cells for other breast cancer cell lines?

No. Often times closely related cell types will require completely different conditions for Nucleofection™. Therefore, you may want to consider performing a full optimization by using the Cell Line Optimization Kit. Please click on the related link...
