Development of a SARS-CoV-2 vaccine is the most effective way to prevent future infections.
The urgency for such a remedy is driving research into available approaches for vaccine development. 

TcBUSTER: fast and flexible stable cell line development for vaccine production

B MOGEN Biotechnologies Genome EngineeringStable expression cell-based systems can offer a faster and more reliable strategy for vaccine production. Novel production systems using mammalian or insect cell cultures will be needed to overcome the limitations of current stable cell line systems in order to produce large amounts of vaccine as quickly as possible.

TcBusterTM, the transposon gene-editing system from Bio-Techne’s B-MoGen brand, can accelerate the development and production of your protein subunit or virus-like particle vaccine by giving you a stable cell population in as little as three weeks, and clonal cultures in six weeks. The generation of stable over-expressing cell lines using our system offers several advantages:

  • A faster, stable cell line generation than when using virus-mediated, CRISPR and plasmid systems alone
  • Stable integration of multiple transgenes in one transfection
  • Higher protein-producing clones compared to stable cells created by site-specific integration
  • A high integration rate that facilitates identification of a high producing clone
  • Sizable protein yields produced from mammalian, chicken and insect cell lines
