TcBuster™ Non-Viral Gene Engineering
From Proof Of Concept To Process Development
Realize the potential of gene engineering by using TcBuster to deliver your genes of interest. Gene editing is a powerful tool for fine tuning cell phenotype in immune cell and regenerative medicine therapies, and it can augment therapeutic effectiveness by increasing cell potency and persistence in vivo.
Partner with our experts to engineer T cells, NK cells, feeder cells, and induced pluripotent stem cells (iPSC) for your cell therapy program.
Why Use TcBuster For Gene Engineering?
TcBuster is a non-viral transposon system that enables stable gene transfer into mammalian cells. It supports the rapid generation of transgenic cells and is a valuable tool for both proof-of-concept and manufacturing scale process development. Gene editing with TcBuster has widespread applications including:
- Cancer immunotherapies – introduction of chimeric antigen receptors (CARs) or TCRs; inactivation of negative regulatory molecules; masking therapeutic cells from host immunity
- Gene therapy – delivery of genes into host cells to correct genetic defects
- Disease models – development of animal models carrying disease-associated molecular variants
- Drug discovery – modulating expression of proteins that serve as drug targets
- Diagnostic tools – upregulation of proteins for detection of infectious and non-infectious diseases
- Vaccine development – stable overexpression of viral proteins to elicit protective immunity
Overview of the TcBuster Transposon Mechanism
TcBuster is a large capacity transposon system that enables transfer and stable integration of genes of interest (GOI). TcBuster can replace the use of retroviral and lentiviral vectors, leading to significant time savings during the development of cell therapeutics.
Comparison of TcBuster and Virus-Based Systems
Sidestep the hurdles of gene engineering with lentivirus systems by using a non-viral method. The use of TcBuster avoids common viral method challenges including low transduction efficiency, inconsistent reagent availability, and an insecure supply chain for GMP-grade virus.
Virus-based gene delivery (e.g. with lentivirus or AAV) involves packaging of the GOI into the viral vector followed by transduction of target cells. TcBuster transposons can be quickly generated and electroporated into target cells. As shown in the graphic below, TcBuster protocols eliminate the lengthy step for viral vector packaging.
Enhance your cell engineering process with TcBuster and
- Shorten your cell engineering timeline and reduce the risk of delays.
- Integrate larger cargo sizes than with standard viral based methods. AAV can typically deliver 4-5 kb of DNA, while TcBuster can deliver >10 kb (enough for 2 TCRs plus an accessory protein).
- Maintain high efficiency gene transfer and stable expression. This enables rapid generation of transgenic mammalian cells with limited secondary effects and no selection steps.
- Reduce the costs of genetic modification.
- Exploit the flexibility of TcBuster to carry out additional gene editing techniques in one operation.

TcBuster is our proprietary transpose transposon genome engineering technology. Transposons are a virus-free way to over-express a particular protein in a cell line. Like the other systems it's a cut-and-paste transposon so you deliver your gene of interest (GOI) within a plasmid that's flanked by sequences that TcBuster recognizes. It cuts out your GOI and randomly inserts it into the genome. TcBuster is a virus-free way to overexpress pretty much any protein of interest in a cell.
