Reversible transgenesis that leaves no trace behind
One of the advantages of the PiggyBac Transposon System* is the reversibility of the integration event. With the Excision-only PiggyBac Transposase, delivered by transient transfection of the Exicison-only PiggyBac Transposase Expression Vector, you can remove any DNA integrated into the genome using the PiggyBac Transposon System. After removal of the PiggyBac insert, the genomic DNA is restored to the original sequence with no residual PiggyBac sequences left behind, resulting in a truly footprint-free removal.
Both the Excision-only PiggyBac Transposase and the Super PiggyBac Transposase (Cat.# PB210PA-1) recognize transposon-specific inverted terminal repeats (ITRs). While the Super PiggyBac Transposase has both excision and integration activities that enable the enzyme to mediate removal of the ITRs and intervening DNA from one location (the vector) and insert that DNA fragment into another location (the genome), the Excision-only PiggyBac Transposase only has the excision activity. Thus, the Excision-only PiggyBac Transposase can be used to remove DNA segments from the genome that are bordered by the PiggyBac transposon ITRs.
With the PiggyBac Transposon System, you can:
- Make transgenic cell lines with a single transfection
- Integrate multiple PiggyBac Vectors in a single transfection
- Insert an expression cassette into human, mouse, and rat cells
- Deliver virtually any-sized DNA insert, from 10 – 100 kb
- Choose from PiggyBac Vectors that express your gene-of-interest from constitutive or inducible promoters and include a variety of markers
- Determine the number of integration events with the PiggyBac qPCR Copy Number Kit (# PBC100A-1)

How It Works
How It Works
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.
- 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.
- The Super PiggyBac Transposase inserts the ITR-Expression Cassette-ITR segment into the genome at TTAA sites.
- The Excision-only Super PiggyBac Transposase can be used to remove the ITR-Expression Cassette-ITR segment from the genome, for footprint-free removal

Reverse transgenesis with the PiggyBac Transposon System’s footprint-free excision process
Figure 2. SBI’s Excision-only PiggyBac Transposase is integrase-deficient but excision capable for reversible transgenesis. (Left panels) Comparison of the integration abilities of the Super PiggyBac Transposase (Cat.# PB210PA-1) to the Excision-only PiggyBac Transposase upon co-transfection with a GFP-expressing PiggyBac Vector. The very low number of GFP-positive cells in the sample co-transfected with Excision-only Transposase versus the numerous GFP-positive cells in the sample co-transfected with the Super PiggyBac Transposase demonstrate the poor integration abilities of the Excision-only enzyme. (Right panels) We inserted a GFP expression cassette into the genome, and then inactivated GFP expression by disrupting the open reading frame with a PiggyBac transposon. Successful use of the Excision-only PiggyBac Transposase restores GFP function, leading to GFP-positive cells. Restoration of GFP fluorescence also demonstrates the seamlessness of excision—the GFP coding region would remain disrupted if the transposon sequences did not get completely removed.
