Study the balance of T cell dynamics in autoimmunity, inflammation, and cancer

Simplify your studies of T cell dynamics with SBI’s ready-to-use, pre-built Treg and Th17 vectors and cell lines. With pMSCV-Human Foxp3-EF1α-GFP-T2A-Puro for Foxp3 Overexpression, you can choose between three different ways to study Foxp3 overexpression from the MSCV promoter for strong expression in hematopoietic and stem cells:

Lentivector-based for transfection-resistant cell lines

Create stable Foxp3-overexpressing cell lines by integrating the MSCV-Human Foxp3-EF1α-GFP-T2A-Puro expression cassette into the genome using SBI’s highly regarded and reliable lentivector technology. With our lentivector technology, you can take advantage of our high-titer lentivector packaging system to efficiently deliver your Foxp3 overexpression cassette to cells using transduction—great for transfection-resistant cell lines.

PiggyBac Transposon-based* for infection-resistant cell lines

Create stable Foxp3-overexpressing cell lines by integrating the MSCV-Human Foxp3-EF1α-GFP-T2A-Puro expression cassette into the genome with SBI’s easy and consistent PiggyBac Transposon System. With our PiggyBac Transposon System, you get easy and consistent transgenesis for Foxp3 overexpression in infection-resistant cell lines.

Pre-built Jurkat cell line to save time and labor

Quickly get your Treg studies off the ground with our pre-built Jurkat cell line that already has the MSCV-Human Foxp3-EF1α-GFP-T2A-Puro expression cassette integrated into the genome. We transduced Jurkat cells with the MSCV-Human Foxp3-EF1α-GFP-T2A-Puro expression cassette and have validated Foxp3 overexpression, so you don’t have to—just culture cells and start your studies.

*Customer Agreements

Academic customers can purchase PiggyBac Transposon System components for internal research purposes for indefinite use, whereas commercial customers must sign a customer agreement for a six-month, limited-use license to test the technology. For end user license information, see the following:

The PiggyBac Transposon System’s Cut-and-Paste Mechanism

The efficient PiggyBac Transposon System uses a cut-and-paste mechanism to transfer DNA from the PiggyBac Vector into the genome. If only temporary genomic integration is desired, the Excision-only PiggyBac Transposase can be transiently expressed for footprint-free removal of the insert, resulting in reconstitution of the original genome sequence.


Figure 1. The PiggyBac Transposon System’s cut-and-paste mechanism.
1. The Super PiggyBac Transposase binds to specific inverted terminal repeats (ITRs) in the PiggyBac Cloning and Expression Vector and excises the ITRs and intervening DNA.
2. The Super PiggyBac Transposase inserts the ITR-Expression Cassette-ITR segment into the genome at TTAA sites.
3. The Excision-only Super PiggyBac Transposase can be used to remove the ITR-Expression Cassette-ITR segment from the genome, for footprint-free removal

Supporting Data

Robust overexpression of Foxp3

Figure 2. SBI’s human and mouse Foxp3 lentivector and PiggyBac plasmids provide robust Foxp3 overexpression. The human and mouse Foxp3 lentivectors Cat.# TCL200A-1 (human) and Cat.# TCL100A-1 (mouse) and the PiggyBac transposon constructs Cat.# TCL200PB-1 (human) and Cat.# TCL100PB-1 (mouse) were transiently transfected into 293FT cells. After 24 hours, cellular lysates were prepared and Western blot analyses performed to detect the Foxp3 protein expression using an anti-Foxp3 antibody that detects both human and mouse proteins. Robust overexpression of both human (lanes 1,3) and mouse (lanes 2,4) Foxp3 proteins compared to the non-transfected cell lysate control (lane 5) can be clearly observed, with tubulin as a loading control.

Figure 3. SBI’s MSCV-Human Foxp3-EF1α-GFP-T2A-Puro Jurkat Cell Line shows strong Foxp3 overexpression. Human Jurkat T cells were transduced with either Cat.# TCL200A-1 (human) or Cat.# TCL100A-1 (mouse) pre-packaged lentivirus and stable cell lines established using puromycin selection for seven days. Overexpression of Foxp3 was evaluated by measuring GFP levels using flow cytometry and Western blot analysis of cellular lysates and using anti-Foxp3 antibody. Both methods show that SBI’s Foxp3-overexpressing Jurkat Cell Line possesses strong Foxp3 overexpression.

    The human FOXP3 EF1 GFP T2A puro piggbac was very excellent product and I am very satisfied with it. Will reorder soon.
