What kind of protocol you recommend for stimulation of human T cells?

For getting the results we present in our datasheet, we recommend the follwing strategy: Cells should be stimulated and cultivated for 3 days before Nucleofection, preferentially on plates coated with 1 µg/ml anti-CD3 and 2 µg/ml anti-CD28 antibody....

Are there any effects on the differentiation of neural stem cells following Nucleofection?

The ability of transfected rat or mouse neural stem cells to be subsequently differentiated into a variety of cell types is well documented in: Olig2 Overexpression Induces the In Vitro Differentiation of Neural Stem Cells into Mature...

Is there a reason why in our Nucleofector Protocols for Primary Human Chondrocytes we include FCS in the pronase and collagenase solutions for preparation of chondrocytes?

Yes, even though this may sound odd since serum is generally known to inactivte proteases. We recommend it in this case, however, because the incubation times are quite long and the cells are stressed by the procedure. The amounts of enzymes should...

Can calcium influx issues affect viability of human Mesenchymal Stem Cells (hMSC)?

Yes. When cells are transfected using Nucleofection™, transient pores are generated in the cell membrane. Generally, these pores disappear within 15 minutes of transfection, but if cells are plated immediately after Nucleofection™ in media that...

Does the GFP sequence in your pmaxGFP control plasmid have a stop codon?

Yes. The coding sequence ends with a stop codon (TGA/UGA).

Can calcium influx issues affect viability or differentiation in Stem Cells after Nucleofection?

When cells are transfected by Nucleofection™, transient pores are generated in the cell membrane. Generally, these pores disappear within 15 minutes of transfection, but if cells are plated immediately after Nucleofection™ in medias that contain...

What antibodies can be used against the GFP produced by pmaxGFP and pmaxFP-Green vectors? What antibodies can be used to detect denatured GFP? What antibodies can be used to detect the RFP expressed by pmaxFP-Red?

Most of the commercial antibodies for GFP do not detect GFP expressed from pmaxGFP or pmaxFP-Green vectors. The origin of the protein expressed by the pmaxGFP control plasmid and pmaxFP-Green is from the green fluorescent protein CopGFP, cloned from...

What is the shelf life of the 96-well Shuttle kits?

The shelf life of the 96-well Shuttle™ Kits is 24 months from date of manufacturing. We guarantee a remaining shelf life of at least 6 months after sending them out of the warehouse.

What are the requirements for direct Nucleofection of mRNA for protein expression?

The mRNA should be capped and polyadenylated. The conditions of Nucleofection™ will be the same as for DNA with the particular cell type, i.e. follow the same protocol and use the same program, except one will likely need to add a much higher amount...

Component B in my Mouse T cell kit became solid at 4°C . Is this normal?

Yes, it is normal for component B to become solid at 4°C. The crystals dissolve at room temperature and functionality of component B is not affected.
