Non-Viral Gene Engineering with TcBuster™ Transposon System
TcBuster is a next-generation non-viral genetic modification system with the potential to deliver therapeutic payloads to various cell types to address a broad range of therapeutic applications.
The TcBuster system includes a transposon plasmid containing the gene of interest (GOI) to be inserted in the target cell’s genome. TcBuster supports the rapid generation of transgenic mammalian cells by allowing for multigene transfer and CRISPR-mediated knockouts in one operation. TcBuster is a valuable tool for both proof-of-concept studies and manufacturing scale process development.
TcBuster can help strengthen your gene engineering process.
- TcBuster reduces your cost of gene modification.
- TcBuster is reliably available throughout your cell therapy manufacturing process.
- TcBuster delivers large genetic cargoes for multi-gene insertions.

TcBuster is a transposon-based technology used to deliver your gene-of-interest safely and randomly into a host’s genome. Watch how TcBuster can help you achieve your genome engineering goals.
Transposon systems are capable of high efficiency, stable integration of genes into the host cell genome. This function enables the introduction of CAR constructs into immune cells to create CAR-T or other adaptive cell therapies.
Overview of TcBuster Transposition Mechanism

Overcome Limits of Electroporation
Our cutting edge non-viral vector transgene insertion platform harnesses DNA transposons for stable gene transfer into any cell type. TcBuster overcomes the three major technical challenges of other transposon systems.
- Insertion efficiency – Greater than 40% insertion efficiency for stable integration in T-cells.
- DNA toxicity – Proprietary techniques reduce effects of DNA toxicity.
- Random integration of enzyme DNA into host genome – Random delivery of transposase as mRNA or protein.
Transposons have demonstrated a safe gene delivery system insertion profile while maintaining high-efficiency gene transfer. DNA transposons enable rapid generation of transgenic mammalian cells with limited off-target effects and stable, reliable gene expression.

Video Transcription: Hear From Our Scientists - What Is TcBuster?
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.
